I got them more for the mild compression support. The fact that they help smooth out all the extra lumps at this point is a bonus for me. They are more comfortable to wear than a support band for my lower back/hip issues. Currently 28 weeks with my fourth, and my varicose veins in my undercarriage area have been bothering me this time around, these have been helping with that as well. I move up from a size medium to a large towards the end of my pregnancies, and the size L/XL fit me perfect.
