Whoops. I clicked B but meant to click D. Pantyhose make the legs look better and more flawless. I think most guys would prefer bare legged because they'd like to see as much skin as they can but I really think pantyhose makes legs look better.
It really depends on the girl. Some girls have beautiful legs that look great all the time both bare and with hosiery, but some girls with obvious issues going on with their legs like keratosis pilaris, cellulite and stretchmarks, stubble, excessive scars or discoloration, or just a lot of uncontained jiggle, should probably wear pantyhose tights if possible.
Bare legs all the way! I actually hate the look and feel of tights especially the clear ones. Remind me of old ladies. Also, girls get extra points for braving the cold and going bare legged in winter!
