Short answer: No.
Longer answer: As far as I know, there are only two reliable methods to make your breast size actually be bigger without becoming fatter. One is by hormones (like when you're going through puberty) and the second one is through surgery.
However, you can make breasts appear bigger by standing up straighter with your shoulders opened up, building up your upper pectoral muscles (muscles beneath your breasts), and slimming down your waist and hips to make your breasts appear larger. You can also make them appear larger with the kind of bra you wear. Be sure that the bra that you are wearing is the correct size.

You can also try push-up bras but they are not very comfortable (in my opinion). Lastly, try wearing clothing that will accentuate your figure, especially around your breast area. Wearing something that draws attention to your bust like ruffles, a low neckline, or something of that sort is also a good way to do this. You can also try taking advantage of patterns and colors in order to make your body appear to be a certain way. Generally speaking, wear bright colors and patterns on your torso to make it appear larger and dark or dull colors for your bottom. In my opinion, the best combination is a striped top with plain, dark jeans, preferably skinny jeans. And only for a last resort, you can try using makeup to make shadows near your bust. This gives off the impression of heavy cleavage.
Hope this helps...
