Just want to say that one of my greatest pleasures has always been to go clothes shopping with the Butch in my life. Usually, I would only get to go along if something special and kind of fancy or dress up was needed, but oh my did I love to help my Butch look fly:-)
In that same spirit, I did a bit of searching last night and found a couple of sites that may or may not be helpful. IDK, really. But you can check them out. If they work for you, great

How to Size Men's Clothes to Fit Women

Living here in the Portland, OR area made shopping for men's clothes for a Butch fairly painless. Especially in
Nordstrom and the mens clothing boutique,
Mario's. First of all there wasn't any negative attitude. Second, both stores could tailor the suits, slacks and jackets to fit. I'm sure Portland has more venues now. I haven't been out shopping with any Butches in a long time.
One of my exes is a very dapper dresser and may have some good ideas to share. You can find her
here, on FB.
Hugs to all of you handsome Butches and
