I wasn’t sure if the sizing was gonna be either too tight so I decided to go with a men’s medium. I mean it’s not too bad it’s a little baggy, a small would’ve fit perfect but after all it is Katsuki and he’s a baggy boy, so technically it fits perfectly haha. I love this outfit and for the price it’s a steal. This was first purchase here and everything went so well!! Definitely can’t wait to buy again
