I ordered this in size 16; the pants were a little big but would work. The vest was WAY to small, like 3 inches too small and the jacket was too small too..shoulder fit was great, just too small thru the stomach area, but since the pants were ok, I ordered an 18 thinking I would wear those pants with th 18 jacket and vest. Well it arrived and jacket almost fit but the vest still way small. I took it to my seamstress and she will be able to sew a piece in the sides of the vest to make it work since it has a jacket over it. The jacket is about an inch from being comfortable, meaning pulls at the button, I will use a clasp type extender to rectify this issue..the bottom line is, it will be an elegant suit after adjustments are made. I have 2 suits, outrageous shipping costs and seamstress fees wrapped up in 1 outfit to wear to a wedding.,so approximately250 dollars. The suit is very nice, good material and I will definitely have a nice suit..I should have had a 20 in jacket and a 14 in pants. I am usually a straight 16 ..top to bottom.
