to be honest, after a certain point a good looking suit does not look good just because of sheer size.
drape and tapering goes straight out of the window. look at the back pants pockets, they become so far skewed it looks strange, and a large person fitting into an otr suit is nearly impossible, as most people store their fat in their midsection, sizing up the jackets enables them to button their suits, but have like 10 inches excess fabric in the shoulders. the other thing is, Men's suits were not designed to have size F breasts, which causes pulling and wrinkles in odd places.
I guess one does get more of their moneys worth in fabric, if a size 58 suit cost the same as a 36s, but uses like double the material...
congrats on losing 90lbs and continuing, not the easiest accomplishment. keep it up, and don't end up like those robust people who have given up.
