Several things I would love...
- Underwear (briefs, boxerbriefs or speedo's)
- Cyclist outfit
- Bikers (sport biker) leathers
- Outdoor: jeans with button fly; underneath some nice tight undies (boxerbriefs with a wide elastic band with the brand name) , heavy belt, pullover with underneath an tight shirt and some heavy hiking boots or sneakers with white tennis socks.
I guess I'm kind of picky but, I like a guy that makes the suit look hot. That said, I do prefer well tailored uniforms, especial military dress whites.
I like me a guy in a wrestling singlet and boots. or as some have posted on here the civil war era soldier's uniform with the knee high boots and the tighter the pants the better.
Full rubber catsuit or leather pants and no shirt. I love the mystery involved where all you can see is the figure with none of the details... well, maybe a couple details...
