There's no such thing as a "normal" set of boobs. Everything from the shape and size of the breast itself to the shape, color, and size of the nipples can vary. Pointy, round, tubular, large, small, and pendulous are all common and healthy ways for breasts to look, according to OB/GYNs Suzanne Gilberg-Lenz, M.D., and Wendie Trubow, M.D.
Asymmetric breasts are a set of breasts where one boob is larger than the other boob. Notably, though, most people's boobs are at least somewhat asymmetrical, according to Gilberg-Lenz, though some might be more so than others. "No human is perfectly symmetric—hands, eyes, feet, and boobs."
Weight. Fat is a large part of your breast tissue and density, so you may notice a difference in your breast shape as you gain or lose weight.
Exercise. Your breasts might look firmer or perkier if you build up the muscles behind your breast tissue by strengthening your pecs.
Age. Your breasts will naturally sag as you get older, so over time, your breasts may become longer and shift to face downward.
Pregnancy and breastfeeding. Your hormones during pregnancy and breastfeeding can make your breasts swell and change the way the fat and tissue are distributed throughout your breasts.
Makeup is a great way to give your breasts some oomph without spending a lot of cash. A pearly body cream can make your cleavage pop, while a dark bronzer can add a cup size or two.
For a lighter, natural lift: A shimmering highlighter can make your breasts look fuller and perkier, but not dramatically so. Put a little bit of pearly cream on your pointer and index fingers, and rub it on the inside of your breasts. The shimmer will give your cleavage a subtle boost, especially in a plunging neckline.
For a more drastic lift: A dark contour can create shadows that give off the illusion of bigger breasts. Use a contour stick a few shades darker than your natural skin tone to outline the inside and the top of your breasts, and then draw lines on the top and bottom of each of your collarbones. Trace all the lines with a matte highlighting stick, and then blend using quick, circular motions.
