These are my favorite leggings ever, and I am not a person whos a big fan of pants in any form. I always wear dresses, but I was trying to plan an outfit for a hip hop concert and nothing I owned looked quite right. I decided to take a risk and order the Electra pattern and wore them with a cute tee and jacket. Since then Ive been buying up this brand of leggings left and right. I cant believe how comfortable they are. Im at least 510 (I think closer to 6 but Im in denial), and these have enough stretch that they don't turn into capris. If I wore pants, I would probably be in the 8-10 range, and both the One Size and L/XL sizes have been perfect. I have an ample derrire with a relatively smaller waist, and these have been flattering in every pattern, even the ones with horizontal stripes. Plus the quality is excellent - the fabric is incredibly soft and opaque, and it washes wonderfully. Im planning to purchase even more.
