Let me just say, if you are on the fence about ordering this dress, just do it right now! I am 5'6 and 140 lbs and the medium fit me like an absolute glove. The collar adds a touch of sophistication, making it perfectly appropriate for my business casual office, but the flowy skirt makes it easy to transition to happy hour drinks. The material feels like high-end linen but softer against the skin. I even wore it with a cute straw bag and oversized earrings like the model and felt like a million bucks!
