It's not easy finding choices in your size and then options for a better fit. Anytime you are able to stop in a mens store try on anything you can find in 36S. Once you find the cut/brand that fits you best you can keep an eye out for better prices. When I am in stores I try on different brands for fun. Brioni is the best fit for me and would require the least adjusting if I was buying RTW. They are the only maker that has the right balance for my posture. Point is, every suit will fit you differently, keep looking for what works for you then stick with it.
