So I bought this maid costume on Amazon and was pretty thrilled when I pulled it out, the fabric didn't feel flimsy, the accessories looked nice. Unfortunately when I went to put it on it was quite the struggle.
The fabric has ZERO stretch, and isn't big boob friendly, so I couldn't get it zipped all the way, and it absolutely crushed my poor tits. My bust is 43" so if you're smaller than that, and have someone to zip it up all the way I'd say go for it, otherwise it's a no lol
I believe it was this one, in XXX-Large: https://www.amazon.com/AvaCostume-Cosplay-Lolita-Halloween-Costumes/dp/B00NWN1FHE/
For men's sizes, I think he's a 36, and he can fit into a regular XL for most women's clothing.
