I don't really know how to make them casually wear each other's clothes... So this ought to be entertaining! Marshall's POV and sorry for the short chapter. Had a lot going on today and very little time to type a chapter and publish it.

"Come on out Fionna!" Marshall called from outside the bathroom.

"No! This is stupid!" Fionna shouted angrily.

"Fionna. This is a big step in our relationship" Marshall said with all seriousness.

"Putting each other's clothes on!?" She shouted once more.

"Please?" Marshall whimpered.

"Marshall, don't make me come out there. Please." Fionn cried.

"Why not? I have on your clothes!" He said.

"Your clothes don't fit." she said.

Marshall instantly felt bad. Her clothes were baggy on him, his clothes were obviously going to be tight on her. Rushing to his closet, he sifted through his clothes until he found what he was looking for. A band tee he had gotten years ago. It was huge on him.

"Fionna, I gave you the wrong clothes. Take these." He said, turning his head away from the door as Fionna snatched up the shirt.

A few moments later, Fionna came out in the huge shirt smiling.

Marshall smiled back. "So how do I look?" He asked, striking a pose.

Fionna doubled over laughing. "You look so ridiculous!" she laughed.

Marshall put his hands on his hips. "I like wearing a skirt. I feel so free." he said whimsically.

Fionna gradually stopped laughing and looked up at him. "So what was the point in this?" she inquired.

Marshall shrugged. "I just wanted to wear a skirt and a bunny hat and not be questioned on my manliness." He said.

"You're so stupid." Fionna said, shaking her head.

"And yet you're still dating me" he smiled.

"I'm dating you because your stupid. You make me feel smarter." she said.

Marshall gave a dramatic sigh. "That hurts. That really hurts." He cried.

Fionna hugged him. "Can we watch a movie now?" she asked.
