She’s dealt with the pressure of thinking about what her body looks like as she ages. This is why I will look into Kate Walsh’s bra size and see how this influences her bra choices.

She has a round breast shape, giving her 34B breasts an equal amount of fullness at the top and the bottom. Despite being younger, Walsh’s Grey’s Anatomy co-star Katherine Heigl also wears a 34B bra, as well as actress Ashley Judd who also wears a 34B.

Kate Walsh can consider 32C and 36A as alternatives to her 34B bra. She can sister size with French actress Eva Green, who has a 32C bra size. She may wear bras with demi cups and wide side panels to contain breast tissue as her breasts sag because of aging.

Benefits of a Small Chest

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 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.

Drawbacks of a Small Chest

Don’t Always Fill Out Clothing

Despite its several benefits, among the most notable disadvantages of having small breasts is the chance that you won’t fill out bra cups or clothing. Particularly when the breast tissue is leaning toward the bottom, the shallow bustline can cause gaping cups.

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.

Might Experience Breast Asymmetry

As you develop breasts, it’s normal for you to experience breast asymmetry. However, this can continue even as you reach adulthood, where the volume of one breast can be smaller than the other. There’s also the possibility that cleavage may veer toward the sides. When you are small chested, every ounce of boobage counts, so having asymmetrical breasts can be frustrating.
