Ash and Misty

While it's not the most "hardcore" anime, you've always had a huge crush on Misty from Pokemon. You quickly decide to make Melanie dress up like her, even if their body types are... Slightly different.

One short trip to a costume store later, and the two of you have your outfits. You're dressed as Ash Ketchum, and Melanie is dressed as your boyhood crush Misty.

Surprisingly, the store actually had a Misty costume that would've fit her dimensions fine... But you didn't buy it. Instead you chose one designed for a teenager--A particularly flat teen, at that.

On Melanie, the already-tiny shorts might as well not be there at all, since they cover so little of her ass. The yellow top is pulled so tight against her chest that it looks like it's painted on. The suspenders frame her swollen belly perfectly. The only two parts of her outfit that fit are her shoes and the red wig.

On the drive over, Melanie keeps trying (and failing) to adjust her costume into something more modest. Luckily, you make it to the convention before the outfit bursts at the seams.

Walking in, you take in the sight of the dozens of booths and hundreds of cosplayers. You even spot a couple of fellow Pokemon cosplayers wandering around.

Leading Melanie further inside, you take a moment to ponder where you will head first.
