Cook has an archetype breast shape, making her 34B breasts look round and full. Even with a petite body, she kept some breast weight from her pregnancy. When choosing nursing or maternity bras, she can also wear 32C and 36A as sister sizes for her 34B breasts.

Rachael Leigh Cook’s breasts are perkier than Josie and the Pussycats co-star, Rosario Dawson, who also wears a 34B bra, and model Natalia Vodianova who wears the same size. Meanwhile, Cook is one band bigger than Israeli actress Gal Gadot, who has a 32B bra size, despite having the same cup size.

Benefits of Small Breasts

Can Easily Wear Low Cut Shirts

Women with smaller boobs can get away with wearing low cut tops and dresses without them looking too risque. Even if you are dancing or jumping around, your breasts won’t show through a wrap dress, a scoop-neck tank top, or a V-neck camisole.

Don’t Have Side Boobs

If you love wearing tank tops, bikini tops, and sleeveless dresses, side boobs can get in the way of having a flawless silhouette. When your breasts are small, there’s less of a chance you have to worry about the dreaded side boob. You can wear anything without thinking about side boobs or bulges.

Can Wear Unlined Bras

There is no padding or foam in an unlined bra because the cups simply have one piece of fabric across them. 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 Small Breasts

Breasts Stay Small as You Gain Weight

If your breasts are dense with tissue, they won’t grow in size even as you gain weight. In turn, they may look significantly smaller as you gain more fat in other parts of your body. However, if you lose weight, the fat in your breasts may also reduce, causing your boobs to become even smaller.

Have a Less of a Figure

Small breasts can give your physique a straight, slim appearance. If your shoulders and hips are the same width, having a flat chest can also make you feel shapeless. Because of this, you might find yourself gravitating towards wearing push up bras most of the time.

Don’t Have Much Cleavage

A to B cup sizes don’t have prominent cleavage like larger breast sizes, even when wearing a plunging V-neck dress. 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.
