Love this romper. fits perfectly, and looks like the picture. i'm 5 ft 7, 125 lbs, and usually am a size 4 or small. i ordered a small, and it fits beautifully. i've worn this a lot this summer in florida, and am getting a lot of compliments. don't be put of by the long sleeves for summer wear- the romper is loose enough and has a nice flow to it.
