This is a very flattering outfit for a wedding as the heavy weight material hangs beautifully.   I had it professionally altered as I am only 5ft 2 so the arm length and skirt length are only suitable for a petite person.   The armhole to armhole measurement on the jacket and camisole is 21.5 in and the skirt, which is half elasticated, is 23.5 in long.   This is an expensive outfit and it looks like it when worn.
