I believe this was a prototype from a RIO brand line. It didn't have a brand tag or washing instructions from the start. I fell in love with the embroidery and design, but the size was just barely right for me, and I ended up not wearing it much after my size changed after I got married. I think it's a size M. It's been home-laundered, but there may be wrinkles. Please refrain from purchasing if you are looking for a perfect, unused item. Price reduced!
