Serena Williams is among the world’s top tennis players. She’s also an entrepreneur and a fashion designer.

As a fashion icon and designer, she has worked to produce clothes that fit and look good on bodies like hers. I’m going to look into the bra size of Serena Williams and how it affects her clothing options and career as an athlete.

What Bra Size Is Serena Williams?

Serena Williams has a bra size of 36D. This suggests that her bust is between 39 and 40 inches wide. She must wear bras with D cups and bands between 32 and 34 inches long.

As someone who needs to run and quickly reach the ball on the court, her 36D breasts can sometimes feel heavy or dragging. This is also why she wears a minimizer sports bra most of the time. She also typically has personalized tennis outfits to control breast bounce when playing.

Just like Oprah Winfrey with a 38C bra size, Serena Williams can use 38C and 34DD as bra sister sizes. Thus, she can sister size with American actress Kat Dennings, who has a 34DD bra size and a voluptuous physique like her. Still, the cup size of Williams is easier to find compared to model Precious Lee, who wears a 36G bra or Charlotte McKinney, who has a 32F bra size.

Serena Williams Measurements

Serena Williams is taller in height, measuring in at 5 feet 9 inches (5′ 9”). It’s estimated that her body measurements are 42-30-40 inches, which translates to a bust size of 42″, a waist size of 30″, and a hip size of 40”. She weighs roughly 157 pounds.

Benefits of Large Breasts

Can Fill Cups Easily

Large breasts easily fill out bras. You’ll avoid the awkward gaping that happens with smaller cup sizes, which can often create awkward lines through your shirt. You can also get away with bras that have minimal padding since your breasts will fill these.

Flattering Bust in Corsets

A corset is worth having if you want to accentuate your assets while narrowing the waist. It’s shapewear that can flatten 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.

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 stuff your bra or wear a push-up bra. Low-cut and V-neck tops can help to further emphasize your cleavage and work great for date nights!

Drawbacks of Large Breasts

More Prone to Neck and Back Pain

Having naturally large breasts means you’re more likely to suffer from back and neck pain. This is because your back and neck muscles need to help carry the weight and alleviate pain from the chest. Your muscles may compensate by leaning forward, affecting your posture.

Get Bra Strap Indentions

Keeping bra cups in place can cause stress and pressure on the straps. Because of this, the straps may dig into your shoulders, pressing the skin and leaving marks. It will be harder if you’re wearing racerback bra for large breasts since you won’t be able to adjust the strap length and tightness.

Breasts Can Sag

Among the biggest drawbacks of having large cup sizes is that breasts will tend to sag. This amount of breast tissue can’t defy gravity, particularly bell-shaped or wide-set breasts. Sagging breasts will be more obvious underneath clothing if you don’t wear a bra that lifts, molds, and supports them.

Serena Williams has a 36D bra size. Her breasts are big and heavy enough to require bras with exceptional support, much like sports bras for running with large breasts. If you have this bra size, it helps to choose bras with thickly-lined cups and broad, elastic bands for optimum lift and support.
