Dress... 100% polyester Inner dress... 100% polyester The size is listed as free size, but I believe it's around a Medium. I purchased this several years ago and only wore it once. There are no noticeable stains or snags. The dress is a pale pink, like cherry blossom petals. There's a zipper on the left side near the armpit, making it easy to put on and take off. The back features a ribbon and decorative covered buttons. The inner dress is a champagne gold color. It has straps, and the shoulder strap length can be slightly adjusted. There is one spare covered button for the dress, which I will include. This dress can be worn not only in the summer but also in spring and autumn by layering a cardigan. It will be folded compactly and shipped in simple packaging.
