Jon overlooked the shirts at his disposal. It was quite obvious that all of them were meant for girls, hell, there was even a Hooters shirt in there! Jon really didnt want to put any of these on but he had very little choice: it was either putting on some over-the-top girls shirt or going out in the nude. Given that Jon had no idea where he was, he decided that the first option was probably best.
He still had to choose which one he was going to wear. He decided to pick his shirt like you would do on a multiple choice test: crossing off al the ones you dont like to get to the best answer.
Well, Jon certainly didn't want a shirt with 'daddy's girl' written on it. What kind of self-respecting boy wears that? It came across as way too tacky, so that was a no-no.
The second shirt said 'We're not sisters, but we are twins". Jon didn't really understand what was meant by that but he guessed that it required another girl to wear that shirt as well. Considering there was no other shirt and there weren't any girls in the room, he couldn't pick that one either.
The third shirt, obviously a hooters shirt, was quite obviously ignored as Jon didn't want to think of what people would say of him if he'd walk around as a guy with that on.
He thus had 2 shirts left: one, a crop top that was hot pink and probably meant for a bimbo, and two, a dark purple shirt that was ripped. He decided to go for the first one, even though it was really degrading and he'd look stupid in it, it was better than walking around in a shirt that was ripped, because he just wasn't that kind of guy.
So Jon put on the pink crop top which was obviously meant to accentuate a girl's body. He decided to open the door and head into whatever was outside. He hoped that he could get back soon enough or he worried someone would spot him in this ridiculous shirt.
