My measurements (with my weight evenly distributed in my body) is 5'8 hgt, 262 lbs and loosing, 40 L cup, med. size belly, thicker things and butt. I purchased this in a 2x. I waiver between 1x and 2x depending on material. I can get away with a 1x now that i've lost and continue to loose weight. I would say this is true to size. A 1x might have been on the more form fitting side so i'm glad i got a 2x to i have a little room. I had to figure out which side the arm was going to come down on so that took a minor second, but all in all i am very please with this set. The color is a tad darker than the photo but no by much. The set is tall girl friendly, light-medium weight and the pants are long (to the floor and i'm 5''8) This can be dressed up or down. Great color for the fall. The back of the top does cover most of my butt if not all of it. I would say to wear a thong or seamless undies. The material does have give to it and also feels good when wearing it. I am very pleased with this purchase and you will be too.
