If you have a great set of pins and gorgeous calves, you can wear patterned tights like these, but if they’re on the more curvaceous side, avoid these kinds of tights as they’ll bulk up your calves and draw unnecessary attention. (Outfit from http://www.anntaylor.com/)
Alternatively, if you’d like to create the appearance of a slimmer, longer leg, look for a pair of knee-high boots which will visually diminsh your calves, I’d also suggest that you wear a pair of pantihose in dark shade that blends with your boots to further elongate your legs (unlike in this picture from Ann Taylor).
