I've only worn a men's suit once. I'm gendered female at work, and don't have any other excuses (and even if I *was* seen as a guy, none of my coworkers wears suits! Cordoroy pants and a knit tie is pretty dressy around my office). But one of my friends was getting married and I kind of absurdly insisted on getting a three-piece suit for the occasion. It was foolish, but awesome. Now I just need more occasions to wear it! Ironically, though, I'm so universally seen as female that people don't even do a double-take seeing me in men's clothes. It's perceived as an idiosyncratic clothing choice, but nothing more. I've got mixed feelings about that-- gives me way more freedom in how I dress, but it's quite frustrating from a gender identity perspective.
The things that I love the most about my suit? The pockets! And the room! I've worn quite a few women's suits in my time, and they're nowhere near as comfortable, and have nowhere near the carry space. Everything but an ipad pocket. (It says a lot about the sexualization vs function of men's and women's bodies and clothing.)
