I have purchased a different style dress from Koh Koh before and I loved it. Figuring that sizing would be similar between dresses from the same company, I ordered this in the same size. Medium was a true to size fit for me in the first dress. This dress.... not so much. The sleeves, top, and skirt may have fit how they were supposed to but the waist was soooo skinny that I couldn't get both arms through! The waist fit perfectly around my head! There's no way in anyone's ever lovin' mind that this dress would have fit the waist measurement in the provided sizing chart. Very sad indeed :s I will be returning this dress.
