While she has a pear-shaped body, her 34B breasts are also common among women with slim bodies. For instance, singer Cyndi Lauper also wears a 34B bra that complements her narrow waist, slender torso, and long limbs.

Rihanna uses puffer jackets, tracksuits, and lace-up tops to highlight her bust. Meanwhile, she can use 32C and 36A as sister sizes in bras. Fellow singer Fergie, who has a 32C bra size, can share a sister size with Rihanna.

Benefits of a Small Chest

Don’t Have Back Pain

Ladies blessed with small breasts can avoid the dreaded back pain. Breast weight can cause your shoulders to move forward, which forces the muscles in your back and shoulder blades to adjust. Having less weight in front means your torso can easily carry your breasts, and the weight doesn’t need to be redistributed.

Minimal Bounce During Workouts

One huge benefit of having small breasts is that they hardly affect athletic performance because of their lack of bounce. It can be painful to have your boobs bouncing around as you work out, and women with small chests don’t have to experience this pain. Plus, small boobs mean you can wear pretty much any sports bra style, even if it has minimal padding.

Can Wear Unlined Bras

Compared to bras with padding, unpadded bras are similar to unlined bras as they simply have one piece of fabric across them. Unlike lined bras, unlined bras typically do not provide much support, so they are perfect for A-B cups. If padded bras bother you, especially on humid days, wearing unlined bras will help your breasts cool off quickly.

Drawbacks of a Small Chest

Might Feel Less Feminine

As you go through puberty and enter womanhood, one key thing that happens is your breasts grow (or, they are supposed to!). So, when you end up with boobs that are A or B cups, you might feel like your figure looks less feminine than you want it to.

Don’t Have Much Cleavage

A and B cups sizes lack prominent boobs like larger breast sizes, even when wearing a plunging V-neck dress with taped breasts. In order to make it look like you have cleavage, you need to wear padded or push-up bras to make your bust look bigger.

Might Feel Self Conscious

It’s normal to feel self-conscious about having small breasts, particularly if you truly want to have large boobs. This can sometimes make you focus on looking for bras that can volumize your breasts regardless of the fit. However, small breasts can be as sexy as other breast sizes.
