Oh man, I never thought to look it up. Thanks!
The Google search wasn't very helpful... and I know a lot of you own suits, so your regular wardrobe is not really that significant. I mean, I know what the measurements mean, I just don't know if you're supposed to get the exact size of your chest or something bigger in order to be able to button/zip something because I don't know exactly how it works.
I guess it's unisex.
