Rosario Dawson is an American actress best known for independent and feature films, as well as voice-over work for various shows. She appeared in Josie and the Pussycats, Kids, and Sin City, among other films.

She has been in the spotlight since 1995 and continues to get attention because of her superb talent and undeniable beauty. I’m going over Rosario Dawson’s bra size and her sister sizes.

What Bra Size Is Rosario Dawson?

Rosario Dawson has a bra size of 34B. This implies that her overbust is between 35 and 36 inches wide. She must wear bras with B cups and bands ranging from 30 to 32 inches long.

Dawson’s 34B breasts protrude from the torso slightly. In contrast, actress Brittany Snow, who also wears a 34B bra, and Jessica Chastain, who also wears a 34B both appear to have perkier breasts because they have a narrower waistline than Dawson.

Rosario Dawson can size up to 36A if the band feels a bit tight on the underbust. Meanwhile, she can go up to 32C if her breast tissue spills out of the cups. This means her bust measurements are nearly identical to those of American actress Anne Hathaway, who has a 32C bra size.

Rosario Dawson Measurements

Rosario Dawson is average in height, measuring in at 5 feet 7 inches (5′ 7”). It’s estimated that her body measurements are 35-26-35 inches, which translates to a bust size of 35″, a waist size of 26″, and a hip size of 35”. She weighs roughly 132 pounds.

Benefits of a Small Cup Size

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.

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 Go Braless

One of the best things about being small-chested is that if you don’t want to wear a bra, you don’t have to! At their core, bras are meant to support your boobs, and when you are an A or B cup, you don’t need a bra for this purpose.

Drawbacks of a Small Cup Size

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.

Gaps Form Between Your Boobs and the Bra

When you have A-B sized breasts, it’s not uncommon for a gap to form between your chest and the bra you’re wearing. This is because your boobs are not large enough to fill the bra. Even if you try sizing down to a smaller bra, you might experience this issue.

Sports Bras Can Flatten Breasts Too Much

Sports bras are a must-have in every woman’s wardrobe, even if you have small breasts. However, some sports bras have the potential to flatten your chest by compressing more breast tissue. It’s like watching your small breasts disappear once you wear a sports bra.

Rosario Dawson’s bra size is 34B. Her breasts aren’t that heavy to require full-coverage bras, yet demi cups that contour the breast tissue can make her bust look more proportional.
