On a woman, Nice tight jeans (or a skirt, not hooker short, but short), with some high heels, a nice blouse and RED lipstick.
On a guy, some slighty sagging jeans (enough some I can see his underwear, but not dragging the floor) some Timberland boots, and a wife beater (or just a normal T shirt) ... Well, honestly, any guy sagging he right way...
Doesn't take much to make me happy.
