How to make my boobs look good in this?

link

So I don’t have fake breasts, but I’m not flat chested either (32D). However, my breasts are relatively wide set so I need a bra usually to give me any type of semblance of cleavage. Is there a way to like tape them or something to keep them looking right? I’ve never owned a deep v type top or outfit so I don’t know how to go about this since conventional bras won’t work. I don’t even know how to keep my boobs from falling out lol
