This was fits small to size, the L/XL probably fits like a medium? it fit me nicely but it was pushing it LOL. It also had a weird fishy smell to it that lasted the whole nice even after airing it out so that was annoying.

I read the reviews and everyone said to size up. I’m usually an XS, but I ordered the S/M and it fit perfectly. I ordered 3 different costumes and this one was by far my favorite costume. I probably won’t wear the glasses because they’re huge , but everything else is great.
