Kylie Jenner is a well-known American reality television personality and entrepreneur. According to Forbes, her successful cosmetics business has earned her the title of the youngest self-made billionaire.

She also established herself as a fashion icon with a daring sense of style. For this reason, I’ll discuss Kylie Jenner’s bra size and how it affects her fashion choices.

What Bra Size Is Kylie Jenner?

Kylie Jenner’s bra size is 34B. This implies she needs to wear a bra with B cups to support her bust, measuring from 35 to 36 inches. A band ranging from 30 to 32 inches also helps shape her breast tissue.

She is one band size longer than her sister, Kendall Jenner, who wears a 32B bra. When struggling with gaping cups or a tight band, Kylie can size down to 32C or go up to 36A. This lets her experiment with various bra styles that look edgy, chic, sporty, or sexy.

B cups are typical among women with full-figured or hourglass bodies. For instance, singer Billie Eilish has a 33B bra size, with shoulders and hips that are proportional to the width of a defined waist.

Kylie Jenner Measurements

Kylie Jenner is average in height, measuring in at 5 feet 6 inches (5′ 6”). It’s estimated that her body measurements are 38-25-39 inches, which translates to a bust size of 38″, a waist size of 25″, and a hip size of 39”. She weighs roughly 127 pounds.

Benefits of a Small Chest

Minimal Bounce During Workouts

One huge benefit of having small breasts is that they hardly affect athletic performance because of their lack of bounce. It can be painful to have your boobs bouncing around as you work out, and women with small chests don’t have to experience this pain. Plus, small boobs mean you can wear pretty much any sports bra style, even the ones that have a light lining or unlined design.

Easier to Buy Clothing

Whether you’re shopping online or in stores for clothing, tops and dresses are often initially designed for women with smaller boobs. This gives you more options, and it also means that you won’t need to worry about getting custom-tailored clothing most of the time.

Can Easily Wear Low Cut Shirts

Women with smaller boobs can get away with wearing low-cut tops and skin-tight bodycon 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.

Drawbacks of a Small Chest

Don’t Have Much Cleavage

A to B cup sizes don’t have prominent cleavage like larger breast sizes, even when wearing a plunging V-neck dress. In order to make it look like you have cleavage, you need to wear padded or push-up bras to make your bust look bigger.

Might Feel Less Feminine

As you go through puberty and enter womanhood, one key thing that happens is your breasts grow (or, they are supposed to!). So, when you end up with boobs that are A or B cups, you might feel like your figure looks less feminine than you want it to.

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.
