I love this dress. It's nice quality and has pretty details. The size is exactly the same as says on the size chart, however if you're worried your bust won't fit or sth you might have to size up. I bought an S but I think next time i'll buy a dress it'll be an M. But that might just be a preference since i'm used to wearing oversized clothes.
For reference I weight 55 kg and am 168cm tall. (waist: 70, hips: 96)
Overall, it's a good JSK. (I didn't buy the chiffon top when buying the dress so no opinion on that.)
Oh, and the detachable bows are good quality, which is a pleasant surprise since they are usually questionable lmao.
The shipping was faster than expected, the only thing that pains me was the shipping price, but that's also to be expected ig.
