Maternity underwear?

Br

Have you bought maternity underwear? Which do you like best? I see there's fold over, over the bump, and under the bump? I can't tell which would be best for me, as my body doesn't compare to the "pregnant" models. I had a belly before the baby, though I am only 5'2" and 135lb. Any suggestions? I feel like under the bump underwear would accentuate the "fat roll".
