Don't be that guy

The thing you're looking for is a push-up bra :)

I have one but it doesn't make them look like that!

Make sure that you are wearing the right size. A lot of women just stick to the same size they picked at 16, even through weight fluctuations, pregnancy, etc. And even the size you started out with is usually wrong unless you actually get measured. Also, there are several different styles of push-up bra, and some styles work better/worse depending on your breast size.

@Jensensbooty contouring, not just for faces.
