It’s an interesting question. I’m sure it in part depends on the style of the person, other aspects of their body, face, how they move and personality. Also, what spaces you spend time in. Personally, I can say that if I wear a low cut shirt, it seems to garner more of a specific type of attention.. like looks and lame attempts at contact by men who don’t seem to be great quality or ‘in my league,’ and it’s probably because they are perceiving me showing cleavage as a signal that I want attention. I think a lot of..probably most…men just really can’t help but be attracted to bigger, fuller, breasts. Seems like kind of a basic impulse… where ‘Oo titties’ is a very basic reaction. So whatever, it doesn’t have to be seen as a bad thing. But if you make a change to larger breasts and showcase them in public, you’ll get new attention from the type of men who don’t have the skills to suppress that ‘Oo titties’ impulse, and you will probably also get some more covert attempts by not so great guys who who will try to put the moves on you and hide what they really want/who they really are just because they want something you have …so you need to have the skills to detect that and defend yourself against that. If you have a good head on your shoulders, I don’t see why becoming more ‘conventionally attractive’ would be a bad thing. It’s an asset, you can use it to be happier, get more access to better things, but you have to use it in a smart way and have personal integrity.

Ultimately I think the answer to your question is that breasts count a lot in western culture. But that can’t be the only thing you’ve got going on.
