Fashion Advice?

Gina • Hello friend🌻
Hello ladies! So does anyone have any fashion advice for girls that have "flat chests" or small breasts? I'm 17 years old and I've recently come to terms with the fact that my breasts are so small, I don't need to wear a bra. But I'm struggling with fashion because sometimes the things I want to wear make me look like a boy, or my nipples pop through the clothing, or my small breasts look saggy through the clothes when my nipples aren't hard. Any advice?
