I bought this costume second hand but never wore it because it didn't fit me. It looks beautiful. Made out of satin. Very elegant. The smallest part of the dress is around the ribcage area (rather than the waist). The dress is a-line and does have the side slit just like the character design. There is a side zipper.
Price: Best Offer
Bust: 34 inches (This part is able to stretch bigger)
Ribcage: 29 inches
Thanks for looking. Feel free to PM me if you're interested or have any questions
