Kate Upton is an American model and actress. She’s widely recognized for gracing the covers of Vanity Fair, Sports Illustrated, Esquire, and Harper’s Bazaar.

Since she started modeling in 2008, her bust size has been a hot subject. I’m going to discuss Kate Upton’s bra size and how it has affected her modeling career.

What Bra Size Is Kate Upton?

Kate Upton has a bra size of 34DD. This means she has a bust that measures 38 to 39 inches. She needs to wear bras with DD cups and bands ranging from 30 to 32 inches to support and lift her heavy breasts.

Daughter of Shelly and Jeff Upton, Katherine Elizabeth Upton was named the Sexiest Woman Alive by People Magazine. Most attribute it to her well defined and widely talked about cleavage. She rose to fame with her modeling in the Sports Illustrated swimsuit issue.

She can size down to 32DDD or size up to 36D bras. However, she’s unlike most runway models with B cups, including Loren Gray, who wears a 32B bra. This is why her 34DD breasts better suit editorial features.

Kate Upton Measurements

Kate Upton is pretty tall, measuring in at 5 feet 10 inches (5′ 10″). It’s estimated that her body measurements are 37-26-36 inches, which translates to a bust size of 37″, a waist size of 26″, and a hip size of 36″. She weighs roughly 130 pounds.

Aside from that, her hourglass body allows her to model clothes others can’t normally wear. Even if she has a bigger cup size than American professional wrestler Charlotte Flair, who has a 34C bra size, they style almost the same because of their smaller waists and bigger thighs.

Benefits of a Big Chest

Kate Upton’s measurements means that she has a large bust.

Get More Body Warmth

Adipose tissue (AKA body fat) provides the fat that promotes breast development and maturation. To keep the body’s temperature stable, it also stores extra energy and calories that can generate heat. So, what does all this mean in simplified terms? Larger cups contain more body heat, which is advantageous on chilly days!

Have Effortless Cleavage

The ability to get amazing cleavage without even trying is maybe one of the most notable benefits of having huge breasts. You won’t have to fill your bra or wear a lifting push-up bra for D cups. Low-cut and V-neck tops can help to further emphasize your cleavage and work great for date nights!

Flattering Bust in Corsets

A trendy corset is worth having if you want to accentuate your assets while narrowing the waist. It’s a snug-fitting garment that can minimize love handles and cinch in your stomach. Most corsets are designed to create a prominent overbust, so having large boobs is beneficial. A big chest can quickly fill the corset for a voluminous silhouette.

Drawbacks of a Big Chest

Prone to Chafing and Rashes

The bra band’s constant rubbing and friction could lead to perspiration, chafing, and breast inflammation. This could cause scars, rashes, and deep grooves around your breasts. Moisture buildup in the folds of your skin around your breasts can worsen the condition if you have an allergy to certain textiles.

Breasts Get Very Large During Pregnancy

Most women will experience breast enlargement during pregnancy. When you already have a large chest prior to pregnancy, the months of being pregnant and breastfeeding can feel unbearable at times. Back pain can increase, and there’s more breast tissue that will feel tender and swollen compared to smaller boobs.

Inevitable Uni-Boob Look

Large breasts can develop a “uni-boob look” when wearing an unstructured bra without underwire. Since there is no structured center gore to help separate the breasts, a uni-boob can also happen when wearing comfortable sports bras for running with large breasts. Lack of support from the cups, straps, and bands can also restrict the breast tissue rather than lift it.


Kate Upton has a 34DD bra size. This is a big bra size for models, although she carries it well by using well-fitting bras and appropriately styling her physique.
