Way too large, I ordered a medium at first per the size chart. I'm 36-30-40 / 140 pounds and the x-small is even a touch big. I kept the x-small as I liked the cut of the dress in general.This faded super fast. It was also hot material.Fits great, looks smashing. Comfortable dress. Convenient.I hiked 40 miles on the PCT in this dress. The technical fabric and zip pocket were fantastic and I'm not sure I can hike in anything else anymore. Ladies - take my word for it and try hiking in a dress! But bring some body glide for the chafing bits...I wear a size 4-6 or "Small" in most things and got the XS in this dress after reading other reviews and it fit me perfectly. I'm 5'4, about 135 lbs. My boobs are relatively small and the shelf bra in this is adequate for keeping me socially acceptable. I wouldn't go for a run in it, but I wouldn't usually expect to go for a run in a dress anyway.Love the style. Wear over pants or skirts. Quality. Great travel clothes.
