Hi, I would like some advice please. I have an RTW grey three-piece morning suit from Hackett. I chose it because I really liked the shade of grey. Over the last year I have lost some weight (about 3/4 stone) and therefore the suit needs altering a bit, mainly taking the jacket and waistcoat in. My question is this, is it possible to alter tailcoats and still keep the contour of the coat and the same distance between the buttons on the back? Any advice would be greatly received. Many thanks.
