Power Mama' Maternity Power Panties Black B

I've gained some weight since I became pregnant and all, I got this shapewear so that it would give me a smooth look under a dress instead made back rolls more visible since it did not go all the way up in the back , came below about 5 inches from bra, I expected a more shape forming material but it is just as thin as tights, besides that my packaged seemed like it was a return , had some fuzz on the fabric like if it had been opened and tried on before
