I think I shared this story before, but it was my first hire with a guy in uniform so it was memorable:
I had regular meetings with a young Army veteran in NYC for about a year. He was about 25 and going to college with his GI Bill. After several meetings, possibly several months, and much fantasizing I asked him to bring his uniform. I may have even promised him some incentive$. He was game. He didn't just bring it, he wore it, traveling in it from his home in Queens to my place in Manhattan. He claimed he got several admiring glances (mostly from women) on the train.
I'm in San Diego now and I've had more meetings with military guys so I've had other chances to indulge my uniform fantasies.
BTW Marines are somewhat tricky in this respect: they aren't really supposed to wear cammies in public (off base). No rule says they can't change at your place though. And the combat boots are pretty good looking with jeans if that's your thing.
