I wear a 34G and the @NOOD Game Changer bra is my ultimate backless top hack! These are essentially pre cut boob tape triangles that you can use to super quickly lift + secure your chest for support that lasts all night long! I have worn these many times, most notably to a SUPER sweaty concert where I was jumping all night, but also to weddings or just under tiny tops! I cannot recommend it enough! I personally wear the size 4. LTKwedding LTKpartywear LTKstyletip
