Motherhood MATERNITYwomens 2 Pack Postpartum Seamless Support Panty Shapewear Briefs

Does these work if you are not postpartum, just a little bump (not pregnant) and just want to look slim on a dress?

Pre pregnancy size medium underwear. I'm 7 months pregnant now and wearing size large maternity underwear. What size should I order these underwear?

I'm having a single incision belly button hysto. Anyone tried these after that type (not ab or 3 incision laparo)? Do they go over the belly button?

What size should I get? 5’5 about 170-175lb at delivery?
