Good maternity leggings?

Has anyone found good, THICK maternity leggings that come up over the belly?  Every pair I try (target, motherhood maternity, Ingrid and Isabel) is so thin and sheer and you can see every imperfection in my butt and thighs. I have a pair of workout pant leggings from fabletics that are nice and thick but they aren't maternity and only come halfway up my belly - I wish they made them with a belly panel!
