Hi, I am looking to kind of buy my first serious suit. I've had a couple before but they were primarily just quickly sized up by a Macy's department store type employee. I'm hoping to find someone who has more knowledge on body proportions, better knowledge on sizing details and what to look for etc. I don't have a large budget to actually purchase a custom suit, but do want to get accurately sized and given some pointers on what to look for when I look around. I am in MN and know of some higher-end suit places like Hubert White, Heime's, and Top Shelf. Is it frowned upon to go in just to get fitted, sized, and given some knowledge without actually buying a suit from the retailer?
