This is a Dinos RULE all-in-one. Size is S. The fabric is soft, and the pants are gaucho style, which makes your figure look good. It's easy to wear for both office casual and everyday use. Depending on the accessories, it's also recommended for weddings and after-parties. The pants have an elastic waistband. There is a zipper on the back. The size is S, but I usually wear M, so I think it might be a little big. I've worn it a few times, but there are no noticeable stains. Thank you for looking.
