Has anyone had experience with this type of bra? My chest is smaller and need a good push! Im worried that the straps won’t stick good or all night though or the push is not good enough. Any thoughts or ideas?

Hey y’all so this is my dress. It’s very full in the back but because I’m self conscious of my bum do you think it’s mandatory I get a bustle? I’m worried it’s just gonna add fullness and make it look worse... what are some if your ideas if you are...
