This is such a fun happy dress. i saw it in the store on the rack that has online returns so there was only one available to try on. it was a size 4 and i usually wear a 6 in retailer brands. i loved the dress and tried it anyway and it fit perfectly which is why i think it runs a bit large. ( for reference, i am 5'2" and 140 lbs., hourglass shape but a bit fluffy in the tummy and upper arms.) it has an empire waistline and a zipper in the back. it is so light and airy and super comfortable. it ha
