In this article, I will explore Katheryn Winnick’s bra size and how it helps her career.

What Bra Size Is Katheryn Winnick?

Katheryn Winnick has a bra size of 32B. This implies her bust measurement is about 33 to 34 inches. She wears a bra with B cups and a band ranging from 28 to 30 inches.

Similar to Anna Kendrick, who also wears a 32B bra, Winnick’s breasts appear slightly perkier because of her hourglass figure. She can also consider 30C and 34A as sister sizes that can fit bra styles like a push-up bra for small breasts.

Having 32B breasts helps Katheryn Winnick in her job as a certified bodyguard and black belt in Taekwondo. She can wear a sports bra for her action scenes without feeling as constricted as a celebrity like Scarlett Johansson, who rocks a much larger 32DD bra size.

Katheryn Winnick Measurements

Katheryn Winnick is average in height, measuring in at 5 feet 6 inches (5′ 6”). I estimate that her body measurements are 33-24-33 inches, which translates to a bust size of 33″, a waist size of 24″, and a hip size of 33”. She weighs roughly 119 pounds.

Benefits of a Small Bust

Don’t Have Side Boobs

If you love matching your bras with 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 fearing it will cause side boobs or bulges.

Button-Down Shirts Fit

Let’s face it – button-down shirts are not made for women with large breasts unless you plan on sizing up 1-2 shirt sizes. Women with A-B cups don’t have to experience this struggle, since their boobs are not busting out of these shirts. You can easily wear your normal shirt size without it feeling too tight on your chest.

Can Easily Sleep On Your Stomach

Another advantage of having small breasts is that you can comfortably sleep on your stomach without it being painful on your chest. There’s no need to toss and turn at night to prevent squashing your breasts. It’s also fairly easy to choose sleep clothes, like a sleep bra.

Drawbacks of a Small Bust

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.

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.

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, sports bras with minimizers 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 as a top.
