Lets talk undergarments

Anyone needing a corset like me? Anyone have any they really like or would suggest that don't cost an arm and a leg? I am not interested in a shape wear thing because they just don't ring sexy and wedding day to me. We decided not to go with the larger sized dress because the boobs would be too big (they still are I need extra padding/push up of some sort) and that would be a tough fix as they are fully shaped and beaded (it would have been a lengthy to almost irritating task for my mom who has been sewing for years), but in turn the waist is small which we knew. My mom is going to take it out either in the zipper or the sides but she suggested I still wear a corset to ensure it fits. I already ordered a waist trainer on amazon because I am fully committed to getting my waist smaller in the less than two months I have! Maybe I won't need the corset by that time but still need ideas for now!
