Ingrid & Isabel A great stretchy tank top is a must-have when you are pregnant. It covers your belly, it flatters your body and it holds up your pants. Ingrid & Isabel makes the best tanks because they are not only long and super comfortable, but they have ruched seams on the sides, which camouflages your belly. Our recommendation is to buy one in every color. P.S. they have other clothes too, but we’re too in love with these tanks to focus on anything else.
