Im currently 6 months pregnant and have already been through 5-6 new bras (larger sizes, no underwires, etc) and none of them fit comfortably. They might be ok for a while but the minute i sit down they dig into my ribs due to my increased belly/chest size. These bra extenders are a life saver!!! I literally have one on all of my bras now and adjust them to fit until the bra isn't too snug. Perfect!
