<human>: Can you succinctly summarize the text in 1-3 sentences?

I know this is going to sound kinda stupid and imature but I really am only looking for some advice on how to deal with this.

So, my girlfriend really likes to wear sleeveless shirts that show cleavage. This alone isn't what bothers me, I never had problems with my girlfriends wearing shirts with cleavage, I actually think it looks good.

The problem is that my girlfriend has small boobs, and so sometimes, if she's not careful, you can actually see her boobs and bra, specially when she leans over.

I hate when she goes out with these shirts because I'm always afraid guys will see her boobs. I don't really have a problem with guys hitting on her because I trust her she'll just tell them to get lost, but I can't seem to get over the fact that she wears these shirts.

I already told her I don't like her wearing those shirts, but she as always wear them, way before we started dating, and it's not my place to tell her what to wear, but I'm having a big problem dealing with this and would like some advice. Thanks.
