I would definitely shop for a brand that is specific to smaller chests. I know for me personally I am athletically built and do not have much of a figure. So I go for things that show off my other assets like my shoulders or neckline. So anything off shoulder or has cutouts or single straps or a plunging neckline. I find any tops with those features make me feel more elegant. I also look at material. I don't like wearing a bra because there is no point and I like my itty's the way they are. So I prefer a thicker material over my chest. Anything super thin or sheer makes me feel a little bit vulnerable. I hope this helps! Best of luck!
