So, I'm beginning to wish I had NOT got a huge, heavy satin dress for a summer wedding. I tried it on the other day and felt huge, not too mention it still needs to be hemmed. Its tight and hard to move in. Any recomendations on good shapewear (bras/bustiers) that will hold me in WELL? Also, Is there a way to alter a dress so it doesn't squeze too much at the top (in the back?) it's strapless, and I don't want the back haqngover thing going on. I do plan on being in better shape by then, but anything helps!
