Jess Greenberg is an English YouTube celebrity, singer, and acoustic guitarist. She gained popularity with her song covers for artists like Bon Jovi, Nirvana, AC/DC, and the Red Hot Chili Peppers.

Her beauty and musical ability have captured the attention of many, earning her more than 1,400,000 YouTube fans. I’m discussing Jess Greenberg’s bra size and what it means for her body.

What Bra Size Is Jess Greenberg?

Jess Greenberg’s bra size is 34B. This means her bust measures 35 to 36 inches. She needs to wear bras with B cups and bands ranging from 30 to 32 inches.

Even though Jess is said to wear a 34B bra, many have noticed that her breasts seem to have gotten larger in recent years. She may have decided to have breast surgery at some point, increasing her bra size from a 34B to a larger bust size.

This 34B breast size is typical among women in their 20s. Her size allows her to wear 32C and 36A bras as sister sizes. Thus, she can wear similar bra styles worn by actress Sydney Sweeney, who has a 32C bra size.

Jess Greenberg’s 34B size means her breasts aren’t too heavy that she’ll be required to wear bras that are made for back pain, unlike American broadcaster Wendy Williams, who has to wear 34FF bras to support her bust completely. However, Greenberg may experience gaping cups if she wears the wrong kind of bra for her breast shape.

Benefits of Small Boobs

Can Easily Wear Low Cut Shirts

Women with smaller boobs can get away with wearing low-cut dresses with taped breasts. Even if you are dancing or jumping around, your breasts won’t fall from your bras when wearing a wrap dress, a scoop-neck tank top, or a V-neck camisole.

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.

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 lingeries or a sleep bra.

Drawbacks of Small Boobs

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.

Breasts Stay Small as You Gain Weight

If your breasts are dense with tissue, they won’t grow in size even as you gain weight. In turn, they may look significantly smaller as you gain more fat in other parts of your body. However, if you lose weight, the fat in your breasts may also reduce, causing your boobs to become even smaller.

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 with minimizing features 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.
