American actress Kate Bosworth rose to prominence for her box-office movie Blue Crush. Her other notable films include Superman Returns, 21, and Still Alice.

She experienced having different bra sizes for her roles because of her varying diet regimes. Since she’s one of Hollywood’s top-tier actresses, I’m going over the bra size of Kate Bosworth and how it influences her career.

What Bra Size Is Kate Bosworth?

Kate Bosworth’s bra size is 32A. With A cups, she has a band measurement of 28 to 30 inches and an overbust ranging from 32 to 33 inches.

She has a banana-shaped body, making her waistline barely narrower than her bust. This makes her 32A breasts look even smaller on the chest, but definitely much bigger than Elliot Page’s who has a 30A bra size. In contrast, Bosworth’s Remember the Titans co-star, Hayden Panettiere, has a 32B bra size.

Kate Bosworth can size down to 30B or go up to 34AA when she’s experiencing weight fluctuations due to diet changes for her roles. This means she has nearly the same bust measurements as Swedish actress Noomi Rapace, who wears a 30B bra.

Kate Bosworth Measurements

Kate Bosworth is average in height, measuring in at 5 feet 5 inches (5′ 5”). It’s estimated that her body measurements are 33-23-34 inches, which translates to a bust size of 33″, a waist size of 23″, and a hip size of 34”. She weighs roughly 115 pounds.

Benefits of Small Boobs

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.

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.

Little to No Sagging

Gravity is the enemy of breasts, especially since it can cause sagging. However, it won’t affect small boobs as much, and it’s unlikely for your small breasts to sag even when going braless. Whether you have A or B cup breasts, your boobs will look naturally firm and perky as you age.

Drawbacks of Small Boobs

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.

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.
