GT, I need your assistance. I'm trying to pick out some running tights (full length, not ankle length), and one thing I don't see in the reviews are whether the tights are OK for people with big butts and thighs but small waists. I have a couple of pairs of Lululemon pants that I wear running, but they sag somewhat in the waist, and I ended up getting chafed and getting a scab on my stomach because they kept falling down and my Ipod headphones poked out and rubbed my skin raw. I have a Nike pair that doesn't sag, but is there any other brand you're aware of that would work?
