Black swing dress stretchy sz xl new

Muxxn, black, size XL, thick fabric, well structured, very stretchy, With tags, no flaw, it’s a little wrinkly being in the shipping bag. I never really opened it and I got it for a party that we didn’t end up going to. Really good quality so I didn’t return it but now it doesn’t fit. Measurements taken from my dress form once adjusted to the size and are approximate but I do my best. I adjust the size to how something would be worn and not skin tight unless it’s bodycon.
