It happens a lot. Although I'm four inches taller and 40 pounds heavier, we can actually wear quite a bit of each other's wardrobe. She likes loose layers and I like things snug, so that helps. Just recently, I discovered that I fit into her wonderful collection of girl jeans, Apparently her curvy hips and butt require roughly the same amount of space as my thicker waist, slim hips, and no butt. She had a pair of upscale (like $80 from Nordstrom) Blue Essence jeans with flared legs that were too long for her, so she said they're now mine. The flares do a nice job of making my feet look smaller, and, with padded panties, have a nice girly shape. It's my new everyday uniform. I can also wear a lot of her tops, and she mine.

Then I had an older lounge/sleep set in red fleece. I had forgotten that it was a set, then found the top way back in the closet. Got both parts out and washed them, then she decided that was hers from now on. She likes warmer stuff in the cold weather, so there ya go.

So we have plenty of things that used to be mine and are now hers, and vice-versa, as well as a bunch of stuff that we share. Out of luck with shoes, though (10 and 13).

Like some of the others here with totally supportive wives, I do consider myself to be unreasonably lucky.
