I opened this thinking it would likely have to be a return. So I'm a little surprised to find that this $20 dress fit me so well. I'm tall (5'9-1/2") at 135+/-lbs and got a medium. It's 100% rayon, machine washable, and arrived fairly wrinkled, but steaming it will fix that. It doesn't even look THAT bad wrinkled (thinking of when pulling it out of a suitcase while on a long European tour in hot weather). My first choice wasn't yellow, but that is what I selected since the colors I preferred were sold out in my size. I'm fair-skinned and can't take a lot of pattern or deeply rich colors, so this pastel yellow worked somehow, in spite of the busy pattern.
