I'm thinking of two options. One is a strapless bra with a bra converter to wear with my dress. I'm wondering how well this works, and if the bra would stay on. I was also wondering if anyone has used a bustier, and if that is a good option. I need something with a somewhat low back because of my dress. And I know there is the option of putting cups in, I'm just wondering if anyone has any input/experience with either of these two. Any advice would be appreciated. Thanks!
