To wear or not to wear

I love the look of the American Apparel leggings, its something new and bold. But without a store nearby I'm left to determine whether the look will be right on me. I love the black eel and the gutsy red and silver pairs. Of course I will definitely rock them on a night out when I'm feeling fierce, and after watching Bravo's "Make Me a Supermodel" the leggings made an appearance in the final runway looks and now the urge is back to buy them. So has anyone bought them, loves, hates...
