Only tried on. There is no size notation, but I think it's for a size S. It's a smooth rayon material and has a very lovely design. Below is the description from the previous seller: ---------------------------------- I'm selling it because it didn't fit and I've kept it in storage. Side slit is 50cm. Bust: 42cm Total length: 118cm The red stain on the tag is original. I think it's the color of the dye, ☻
