I say whatever you are comfortable with.
Initially I want to say "Yes, that sounds sexy" but then I realize that there are so many people who I'd rather not see dressed that way.
Fine if the top covers ya arse and ******... I wear just leggins and a top a lot
Stuff em... if it looks good on you wear it!!!
Well, call the tights Lululemon and the answers are: of course and everywhere! Varying degrees of quality and thickness to tights/leggings.
Fine by me.
It's gotta depend on you. I mean if you are a ninety year old, wear a burka. If you are are reativly young, and in good shape, just wear a baggy t-shirt, no panties, and carry the leggings/tights in a bag. Every guy you pass on the way will probably offer to help you carry whatever it is your buying.
I've gone out a few times wearing black leggings, a long sweater, and black ugg style boots just like the gals wear in the winter. Got a few snickers from the young gals (teenagers) otherwise not much if any reaction at all.
