Ha, yeah I do have a Michael Phelps-esque build with ridiculously wide shoulders and generally weird proportions (I take 20" shoulders on a 41" chest/35" pants waist), so it's always tough for me to find jackets that fit *just right*, and even when they do they still LOOK like they don't fit me. Thanks for the feedback!!
^^^ Perhaps you should look for less waist suppression in tandem with shorter jackets. And instead of flat fronts, look into single or double FORWARD pleats on trousers with a slightly higher rise (11 1/2 - 13" inches at most), and keep your knee and leg opening between 9 and 10". This should de-emphasize the natural broadness of your shoulders while visually reducing the length of your torso and lengthening the appearance of your legs.
Also, have you considered American sack-style suits. They can be tailored to have shape.
(^^^ I'm not intentionally ing my Etsy shop, but this solid navy BBGF sack suit better illustrates exactly what I'm talking about than anything I tried to find on the web.)
