Bought these and a pair of Maternity Shorts and love them both.
I wear normal underwear under these, so they're a 2nd supportive layer meaning I can wear a few times (like the shorts) before washing. I should have bought more haha!
I'm in 2nd trimester and these have grown with me and as I head into 3rd trimester I'll be wearing 24/7 for night time support too.
