Kurt is excited to go shopping with Blaine, and gets jealous when a salesperson (can be a guy or girl) gets flirty with Blaine.
Jealousy
"Just get them, Blaine. You won't regret it."
Blaine looked doubtfully at the bright red fabric Kurt rubbed between his index finger and thumb.
"I'm not going to wear those," he insisted, glancing nervously to the side at the nearby customers and trying to shove the pair of pants back out of sight between the other, less conspicuous clothes hanging on the rack. It was the first time they'd gone shopping as a couple, and Blaine wished that he'd pushed for their usual coffee date instead of letting Kurt loose in the mall.
"You need to own something besides identical blazers. If you transfer schools in the fall - I know you still might not - if you do, you're going to want clothes respectable for public school."
"Yes, because the student body at McKinley is going to be so receptive to a gay guy dressed in tight, hot-red pants. Have you forgotten that you live in Lima, Ohio?"
"This is exactly why you need the pants," Kurt concluded ridiculously, pointing between Blaine and the pair of pants as if Blaine had somehow just established a connection between them.
"How do you come up with that?"
"Because you need to know that you can be yourself even when you're not at Dalton, and not worry about what other people have to say about it. The New Directions have each other's backs, you'd be fine."
Blaine shook his head, still unconvinced, but he let his eyes linger on the pants for a moment longer this time.
Kurt followed his gaze and grinned smugly. "You know you secretly want them. Come on. Just try them on. For me?" Kurt looked up at Blaine and widened his eyes purposely in a transparent attempt at begging.
It was the hopeful, eager glint in his expression, more than the deliberately pleading face, that made Blaine sigh and agree, shaking his head ruefully.
"Thank you!" Kurt almost squealed, grabbing the clothing off the rack and then throwing his arms around Blaine for a moment in a very short, tight hug. "You're going to be so glad you did this."
"Don't be so sure about that," Blaine warned, but he was laughing as he did so, and he let Kurt take his hand and tug him away.
"The dressing room is the other way," Blaine reminded.
"I know," Kurt answered absentmindedly, halting in the middle of the store and gazing around. "We're missing something." His eyes scanned the rows of clothing sharply, and then suddenly lit up. He walked over to a rack and plucked a narrow, neon yellow belt from it.
"You can't be serious," Blaine said, staring in horror at the bright color. "Are you sure those colors don't clash or something?" He looked between the pair of pants and the belt and then up hopefully at Kurt.
There was no such luck, because Kurt shook his head and said confidently, "No, it would if it was on me, but this was made for you. Now we just need to find you a shirt."
"What's wrong with the one I have on?" Blaine asked, looking down in outrage at the forest green Polo shirt he'd chosen that morning specifically because he knew Kurt particularly liked the way the color complimented his eyes.
"Nothing's wrong with it now, but you'd look ridiculous if you wore it with these pants."
"I think maybe what you're trying to say is that the pants just plain look ridiculous?"
Kurt ignored this and put the tip of his index finger thoughtfully between his lips as he scrutinized Blaine, looking him over critically. Then he nodded as if he'd made up his mind about something, and declared, "I've got it. You'll actually like the shirt - I promise."
Blaine allowed himself to be led through the racks of clothes until Kurt lifted a surprisingly understated black, short-sleeved, button-down shirt and held it up for Blaine to see. "Is this okay?"
"Do I have a choice?"
When Kurt nodded quiescently enough, Blaine narrowed his eyes and actually considered the shirt, staring at it hard. "Is there a trick here? It looks… normal."
Kurt beamed triumphantly and added it to the clothes already draped over his arm. "I told you that you'd like it."
Kurt nearly dragged him to the dressing room, and then thrust the clothes into Blaine's arms. "I don't want you to see yourself until everything's on and you come out to look in the big mirror out here, okay?" Kurt instructed.
Blaine gave him a perplexed look before he agreed and disappeared into the stall. There were the sounds of clothes falling to the floor and being slid off hangers, and then Blaine called out, half laughing, "It's a little hard not to look at myself when there are mirrors on either side of me."
"Then close your eyes if you have to."
"Okay, okay," Kurt heard Blaine mumble, and then, a moment later, "What's the difference?"
"You need to see the full effect, all together, or you'll think it doesn't look good and refuse to try everything on. I'm serious here, don't make me come in there to make sure you're not cheating."
"Don't worry, there's no need for that," Blaine assured him, tugging on the pants, which were surprisingly comfortable despite being very tight, and then tucking in the shirt. He groped around for the belt and fumbled to loop it around his waist without looking down at himself. "Is this belt really necessary?"
"Yes," Kurt said, so quickly that Blaine was sure he hadn't had time to even consider the question. "You have to learn to accessorize. I can't believe that two years in a school uniform destroyed your sense of fashion so completely."
"It's possible to accessorize subtly, you know," Blaine pointed out.
"It's also possible to switch up your outfit by doing more than alternating bowties."
Kurt expected Blaine to argue with this, but instead the stall door swung open and Blaine stood in the doorway, eyes still closed. "Can I look yet?"
"Hang on." Kurt placed his hands on Blaine's shoulders and, with gentle pressure, maneuvered him until he was facing the big mirror at the end of the row of changing stalls. "Okay." Kurt's hands disappeared from Blaine. "You can look now."
Blaine opened his eyes and was surprised by the person smiling at him in the mirror. He'd expected to see an uncomfortable-looking stranger in the reflection. Instead, he saw himself, but a confident, bolder, and - though he felt silly realizing it - very good looking version of himself. The black shirt was like something Blaine might have chosen for himself, but it clung to his chest and bared his arms, highlighting the muscles that were toned from years of boxing. The pants were scandalously tight, but in an attractive way, and though they were so bright that they almost hurt to look at, the neon in the belt made them oddly just right.
"See? You look good."
"I should have trusted you," Blaine murmured in Kurt's ear, slipping an arm around Kurt's waist and pulling him close for a quick kiss on the cheek.
Blaine changed back into his clothes and was heading to the check-out when Kurt leaned in and whispered, "You know, you're going to have to transfer now."
"Oh yeah? Why's that?"
"Because you need opportunities to wear this outfit." Kurt reached up and squeezed Blaine's bicep lightly. "You can't keep on hiding all this under a blazer."
Blaine's pleased flush hadn't quite faded from his cheeks as he left Kurt to wait by the exit and deposited the clothes on the cashier's counter, pulling his wallet from the back pocket of his jeans.
"Hey there," said the girl behind the register.
"Hey." Blaine flipped open his wallet and thumbed through the bills inside, glancing up for the price only to see that she hadn't scanned the items yet. "How much is this going to be?" he asked absently, tapping his hand on the stack of clothes.
Before he could move his hand away, hers was on the clothes, too, her fingertips overlapping with Blaine's just a bit in a way that seemed almost deliberate. Blaine looked up in surprise and met her eyes. She was younger than he'd assumed from her low, husky voice - probably eighteen or nineteen. She lowered her eyelids slightly over ice-blue eyes and looked up at him from underneath her long, thick lashes, withdrawing her hand and tucking her waves of deep red hair behind her ear. "Sorry," she said, and took the clothes, passing the tags across the scanner.
She paused when she got to the pair of red pants and held them up, pursing her full lips and then glancing over at Blaine as if she was imagining them on him. "Good choice," she said, leaning across the counter confidentially, as if sharing a secret. "Wish I could see you wearing these, I bet they look hot on you."
Blaine chuckled uncomfortably and nodded, unsure what he was supposed to say to that. A mere thanks seemed out of place.
"Not that you need much help in that department."
Now he looked up at her again, arching an eyebrow and wondering if she was ever going to let him just pay for the clothes and get away.
"My name's Ruby, by the way."
Blaine glanced at the long, red hair and covered his mouth slightly with his hand, trying to hide his amused smile. That can't possibly be her actual name.
A moment later, however, Blaine regretted the gesture, because the motion drew her attention back up to his face, and now he was sure that she was staring at his lips, looking at him like a predator stared down a piece of meat. He felt a flush creeping up his neck, and it only intensified when it struck him that that reaction was the opposite of helpful at the moment.
"That'll be $42.79," she said, this time being the one to recall Blaine from his musings.
Blaine fumbled for the money and shoved a fifty dollar bill across the counter hurriedly, not bothering to count the change she handed back to him. She tore his receipt from the register and scribbled something quickly along the side of it in big, loopy handwriting with a pen that had been lying nearby.
"There you go," she said, handing him the slip of paper.
Blaine glanced down at it to see that she'd written down her personal phone number, and just when he was certain that he couldn't possibly turn any redder, she purred, "Don't hesitate to call the number. We have very good customer service."
Just then, a cool arm slipped through Blaine's and Kurt said smoothly, "Hey, baby, ready to go?"
"Uh, yeah," he stammered, grabbing the shopping bag and trying to pretend that he hadn't heard Ruby call out, "Bye, stranger!" to his retreating back as Kurt dragged him out of the store.
As soon as they reached their car in the parking lot, Kurt let go of Blaine and spun him around by the elbow. "What was that?" he spat.
"That was Ruby."
"She was flirting with you."
"I know, it was so creepy." Blaine chuckled, the exchange oddly amusing now that it was over. "She told me they had good 'customer service.' What kind of a pick-up line is that?"
"Whatever," Kurt snapped testily, and stalked around the front of his car to get into the driver's seat.
Blaine frowned after him, perplexed, and slid into his side. "Are you mad?" he asked.
"Now, why would I be mad?
Blaine raised his eyebrows and waited.
"Maybe it's because you enjoy getting attention from total strangers!"
"She's just a sales clerk that I'm never going to see again," Blaine said, bewildered by the sudden hostility.
Kurt narrowed his eyes sharply. "So was Jeremiah."
Surprised at the venom in the three words, Blaine said blankly, "Just because they're both flirty cashiers doesn't mean I'm going to fall for Ruby."
"Oh, so you fell for Jeremiah?"
Blaine sighed and shook his head incredulously. "You can't be serious." Kurt crossed his arms and looked away, the set of his mouth supremely irritated. The expression was vaguely familiar, and suddenly Blaine realized, "Are you jealous?"
"What?" Kurt said, looking back over at Blaine in mock surprise. "Whatever about a ridiculously unsubtle cashier hitting on my boyfriend would make me jealous?"
"Kurt," Blaine said, reaching forward to take Kurt's hands, "She's a girl. I'm not attracted to her."
Kurt mumbled something indistinctly, and when Blaine tipped his head slightly and furrowed his brow, Kurt repeated more audibly, "Being a girl didn't stop you with Rachel."
Blaine laughed quietly under his breath at the preposterousness of the situation and shifted his grip to hold both of Kurt's hands in one of his own, using the other to turn Kurt's face gently towards him, forcing him to make eye contact.
"Kurt. Ruby doesn't interest me. And it's not because she's a girl. She doesn't know me better than I know myself, the way you do. She doesn't insist on kissing my knuckles after every boxing session. She doesn't zig when I think she's about to zag. You do. I love you."
Kurt was trying to look away again, but this time Blaine was sure it was because of the rosy blush glowing on Kurt's cheeks. "Not yet," Blaine said gently, keeping his hand under Kurt's chin. He tipped Kurt's face up and leaned across the console to kiss him very softly and tenderly on the lips. "I love you," he whispered against the sweet-smelling skin of Kurt's neck as he trailed kisses along the edge of Kurt's jaw. "Don't ever doubt it, okay?"
"Okay," Kurt whispered back breathlessly, reaching over to wrap his arms around Blaine's neck, the bag of clothes and the receipt between them forgotten.
I know I ended up just describing Blaine's "It's Not Unusual" outfit for the shopping, but I was being too lazy at the moment to think of original things they could be buying... and then I remembered Cooper's comment about Kurt picking out Blaine's clothes, and decided that it could work.
