I wear jeans most of the time, so a heavy-duty nylon belt with a velcro overlay would stick out. If anything, I'd prefer to look like a boring Amish dude rather than a guy with a funny belt.
If you're really into the "tacticool" fashion statement, then drop the $90 on a 5.11 nylon belt with the rappelling clipamajigger, because a boring $30 leather belt would really jump out.
As a hetero female, may I just say that I truly cannot remember the last time I noticed ANYTHING about a man's belt (barring cowboy/western belts). Most likely, the last time a man's belt got any kind of conscious reaction out of me, it was probably for being something waaaay too metro or girly. Like, something with rainbows or little cartoon animals.
