Rule #1 go high waisted, you’ll never regret it—the wider the waistband the better you feel.

I try only to buy Lulus on sale but they are sort of definitely the best (highly recommend the Wunder Under Pant)

Alo Yoga is very good

K-Deer are excellent and ~specially designed to avoid camel toe~ lol

My other tip is who cares about cute tops, just worry about structurally sound and COMFORTABLE bras and pants, and just wear old T-shirts you cut the arm holes out of or six-dollar tank tops from Forever 21.
