The detail and build quality of this outfit is great. The seams are straight, no frays or loose threads that I’ve seen, and the material is good quality. It looks, remarkably, exactly as it is shown in the pictures. The little cones that Anya has on her head are worn via little hair clips, which is wonderful. The dress has a good quality zipper on the back, which goes about 1/2 or 3/4 of the way down the back. The gold hem and cuffs feel solid and the trim detail on the hem and throughout the main dress is wonderful. This is a solid costume for cosplay (I purchased for my daughter to wear for Halloween).
The one thing I would mention is that the size chart is a little difficult to read for an American without much experience with taking measurements with a tape or anything like that. I’m afraid the costume may be a little small for my kid (she’s 8, probably 90th-ish on the growth chart, not chunky, but tall). I ordered the 130cm version, and I wish I had enough time to rush a replacement in a larger size.
All in all, outstanding workmanship, build quality and attention to detail are top-notch. You’re going to have to do a better job than I did for ensuring the size will fit properly.
