I pre-ordered this costume in September and it finally arrived today! The customer support was super helpful and responded almost within the same day of me asking what the status was while I was waiting <3
The costume is incredibly detailed, every piece has it's own pattern and texture and it is fairly easy to put together. My order was an XL (cause of my bust size), but it is actually a little too big (I wear M/L in Europe). It is not a problem though, because the belt is very adjustable (with a few buttons) so I can just tighten/fix it like that :) Overall it is very comfortable, you can't move your arms too far up though without misplacing some things, but it was expected with the cut of the dress.
The thigh wraps are unfortunately a bit too tight around my thighs (but not as tight as some other "one size" thigh highs you get from online orders, it's probably fine for most ppl), but thanks to the rubber bands on the inside I can easily fix them in the next few days.
I also ordered the wig and it is perfect! Very full, with 3 colors and super soft! Just need to comb it and put some hairspray on it and it's done!
*not featured in the pictures, but there are bows and bells for the ears included as well!
tl;dr: order it (if you're not sure about the size, go smaller probably)!
