Pants for me, unless the dresses are long, if they're medium then stockings (never bare legged) and if they're super short I like to wear them with pants (jeans or black dress pants) - I even once wore a really pretty short velvet dress with beading by Jones New York with a pair of black dress pants and a small shawl, it gave it that modern indian shalwar kameez look which I just LOVE : )
When it comes to skirts mine are mostly long, so one could say I'm a pants/skirt girl but rarely a dress girl : )
