braless?

so ive been braless before but ive always worn a huge sweater when i do because im scared that people will see. i have really small boobs..and like when girls so braless there is this really nice aesthetic to it. for me my chest is pretty flat and most of my boob is on the bottom part. if you know what i mean. what tops look best to go braless? also how do i act normal with it? i feel like i shy away alot and i dont like it. it's as if i dont want anyone to know i have small boobs. thanks!
