Takes place around season 3, but so far no specifics or spoilers for seasons/episodes, I'll let ya know if that changes. Enjoy :)

Juliet sighed as she wandered around the aisles of the party supply store. Shopping here made her happy, she always loved having people over for a party: Birthday parties, Valentine's Day parties, New Year's Eve parties, St. Patrick's Day parties even though she was Scottish; any party you could imagine, she'd be happy to throw. Unfortunately today she wasn't there for a party…well, not one that she was throwing anyway. She was there for her latest assignment, one that involved going undercover to protect a millionaire at his annual costume party; a very out of season costume party, 6 months after Halloween.

She was glad that at least she wasn't going alone, Carlton, Shawn, and Gus all had to go as well, but her partner was the only one who was more miserable than her about having to go. Shawn and Gus had gladly accepted the assignment, with more excitement than two girls being asked to prom, and had started planning their costumes before they even left the office.

The Chief had held her and Lassiter back though and went over ground rules for their costumes. Her partner had been forbidden to use his usual costumes: detective, instead of head detective, or Dirty Harry. Karen was very insistent that he try not to look like a cop while going undercover and after much debate, his suggestion of going as a 1940's mafia hit man was approved by the Chief. It wasn't until later she found out he chose that because he could use his costume from his tap dance recital and have a gun holster without seeming suspicious.

Surprisingly, it was Juliet who had a more difficult time getting a costume approved by the Chief. All of her suggestions were dismissed until Karen finally told her outright that she was going to stand out more at this party by trying to wear a modest costume. As much as Juliet hated to admit it, she knew Chief Vick was right. The purpose of going undercover was to blend in as much as possible and that meant having to dress in a slutty costume just like every other girl attending the party.

Which brought Juliet back to her current predicament in the party store; she had been wandering the aisles for almost an hour, getting more irritable with each minute that ticked by. There weren't many costumes left in the store since it was long past Halloween, but she was still hoping to find something that wouldn't make her look like a whore in front of her partner and a certain psychic who she knew would never let her live it down.

She scowled at the seemingly abundant variations of naughty nurse and French maid costumes that she passed, and while she had considered a sexy cop costume, she knew that it was too closely related to her job and the guys would think about that costume every time she used her cuffs at work. She glanced at her watch with another sigh, it was only an hour til they were supposed to be at the party and she still had nothing. It seemed hopeless at this point and she was ready to give up, she was sure Carlton could handle it, and even though a party at an elaborate mansion did sound like a really fun case, she wasn't going to risk the humiliation in front of her coworkers, especially Shawn. As she spun on her heel to leave the awful store, a glimpse of red caught her eye and she hesitated before giving in to the gut instinct that had made her pause in the first place and she snatched the costume off the shelf.

As she stood in front of the mirror, Juliet felt a bit self-conscious. She knew the costume looked good on her, but she couldn't help but feel like she was back in high school, going to a Halloween party where gorgeous girls would be dressed in even sluttier costumes, attracting all the attention. It wasn't like she cared about the attention though, she was going to the party for her job, not to get laid. In the back of her mind, a little thought nagged at her, she didn't care about attracting the attention of other guys, but she did care about not being able to get the attention of a certain guy. A certain hazel-eyed psychic to be more precise.

Her phone buzzed with a call from her partner, she glanced outside to see him waiting for her in his car and she adjusted her costume a final time before answering her phone as she grabbed her things.

"O'Hara, call them again, there's no reason for them to be this late!" Lassiter snapped as he scanned the crowd for the idiot psychic and his partner; they were supposed to have been there an hour ago but there was no sign of them. Normally he wouldn't have cared at all, but whenever Shawn wasn't where he was supposed to be, Carlton got antsy and wondered if he had already solved the case or was doing some asinine stunt that would put him in the papers…again.

Juliet rolled her eyes "I've called Shawn three times and Gus twice, and I've texted them both 5 times already. If I call again, I'm going to have a restraining order against me." She told him with a bit of a growl and walked off towards the other side of the party. She'd been pretty on edge too, but not for the same reason as her partner. All night she'd been feeling intimidated; there were gorgeous model-esque women everywhere and she was sure Shawn could have charmed any one of them the second he walked in the door. In fact, she was fairly sure that's exactly what had happened and that was why he and Gus were nowhere to be found. Not that she cared, in fact she knew she should be glad that they weren't around to see her costume; they would only give her crap about it and she would lose whatever bit of authority she had over them. However, that still didn't make her feel any better that there'd been no word from them.

Suddenly she saw two familiar figures emerging from the crowd and making their way over to her. At first, she was overcome with relief to see them, but that was quickly followed by flashes of irritation at their tardiness, amusement at their choice of costume, annoyance at their smug looks, and finally embarrassed because of the intensity of Shawn's gaze on her as he took in her costume.

Before she could interrogate them on why they were late, Shawn spoke up, addressing his comment to his friend but looking at Juliet "Gus, remind me to apologize to Dennis, apparently blondes can make a very sexy Wonder Woman." He glanced up and down at her costume again, from the boots to the lasso, to the form-fitting, one piece costume and then the tiara and wristbands to complete the look.

Juliet rolled her eyes and forced herself not to blush or smile at the compliment. "You guys are an hour late and neither of you bothered to answer your phones, care to explain why?" She arched an eyebrow and crossed her arms so Shawn would take his gaze off of her cleavage.

"Uhh yeah sure I can explain" Shawn said with a nod as he raised his gaze and smiled at her "These costumes are a lot harder to put on then it looks, Gus and I really underestimated the time it would take to suit up." Of course he couldn't tell her that they'd actually arrived early but had been wandering the mansion trying to find hidden passages in case a Clue style murder mystery happened and they needed to escape or hide.

She gave him an incredulous look as she glanced at their Ghostbusters costumes "Yeah getting into a jumpsuit can be a bitch" she deadpanned and just gave him a 'that's bullshit' look. However, she was fairly confident they hadn't been off having sex with any of the women here since there costumes seemed in good condition and not messed up or anything like that.

"It can be" Shawn said with a nod "Especially when Gus thinks he's Harold Ramis when he's obviously Ernie Hudson."

"That's just racist Shawn, I don't have to be the black guy just because I'm black! I'm also smart so I would totally be Spengler! At least I'm not delusional like you, you think you're Bill Murray when you're obviously Dan Akroyd." Gus huffed and adjusted his costume, trying to have a Ramis persona.

Shawn gasped at that "Are you kidding me? His hair is terrible! I'm definitely Bill Murray!"

Juliet cleared her throat at that and replaced her amused smirk with an annoyed scowl.

Shawn just smiled and ignored the irritation in her expression "Don't worry Jules, you'd definitely be Sigourney Weaver. In fact, Gus and I saw a ladies version of our costume, it's a little uh different, but I'd be happy to get it for you. I know what you're thinking, Dana Barrett never was an official Ghostbuster, but I think we can overlook that detail."

She just gave him a look at that; after spending an hour staring at slutty outfits today, she was well aware of that costume…in particular how short and tight it was, it left even less to the imagination than what she was currently wearing. "I think you can save that costume for your dreams." She told him with a hint of a smirk "Or maybe you can wear it and be Dana and Gus can be Louis Tully."

They both made a face, Shawn at the vision of himself in the girl's costume and Gus at her suggestion for him "But Rick Moranis is Canadian!"

Juliet just chuckled, very pleased at herself for the reactions she elicited "At least I got you two to stop bickering, now get to work and keep an eye out for anything suspicious." With that, she turned on her heel and walked away.

Several hours later, the party was still going strong but there was no suspicious activity at all. Even the host of the party had drunkenly admitted that he might have been overly paranoid by hiring them as security detail for his party. Still, they had to follow the Chief's orders and stay until the party ended. Juliet didn't seem to mind as much once she started mixing up the non-alcoholic drinks with the ones that were quite strong. Normally she would never drink on the job, but it really was a waste of time. Also the drinking may have had something to do with the look Shawn gave her whenever she met his gaze; it made her feel like she needed a shot of something strong to soothe the weird feeling in her stomach.

When she realized her cup was empty, she set it down and set off in search of somewhere to pee. The bathroom she found was bigger than the living room in her apartment and she was a little hesitant to use it at first and wandered over to the window, which overlooked the ocean. She spent some time watching the moon reflect off the waves and then noticed a light flick on in her peripheral vision and glanced over, surprised that the mansion was so big that it wrapped around and there was another wing directly across from the one she was in. The light that came on seemed to be in some sort of library; she could see into the windows but she didn't pay much attention and went to relieve her bladder. That turned out to be quite the process because she had to pull her costume down completely just to pee. After she finished and washed her hands, she was getting ready to pull up her costume again and noticed she'd left the curtain open on the window.

As she went to close it again, she noticed people moving around in the library. At first she was suspicious and thought it could be intruders, but then noticed the costumes and smirked at Shawn and Gus wandering around. While she started to wonder why they were in there, Shawn turned towards the window and looked out across the small courtyard. She didn't even have time to try and hide before he saw her and his eyes widened; he could only see her from the waist up, but still it was a naked Jules from the waist up.

Juliet blushed at being caught like this and was trying to figure out how fast she could escape, but her feet weren't moving and her hand was holding the curtain open instead of closing it. She wasn't sure if it was the alcohol making her this bold or just some part of her that enjoyed giving Shawn something she knew he wanted. Whatever it was made her feel confident and sexy and leaned closer to the window even though she knew he already had a good view because she could see his expression very clearly. Briefly she glanced away from his face to make sure Gus wasn't watching, but he was completely clueless, examining the bookshelves on the opposite wall.

She looked back at Shawn who was practically drooling by now and she smirked before sliding her hands over her stomach and then up higher to gently cup her boobs while he leaned closer to the window that was trapping him in the library. After giving her tits a quick squeeze, she dropped her hands and then pulled her costume up. She didn't even glance back at him as she left the bathroom.

Juliet wasn't stupid, she knew he'd be trying to find her after that little show and while she had enjoyed the bit of a peep show she'd given, she wasn't ready for what came after that. She went to find her partner and gave him an excuse about getting sick in the bathroom and needing to go home. He didn't pressed for further details and she quickly left and caught a cab back to her apartment, smirking happily the whole ride home.
