Kourtney Kardashian is a well-known celebrity and reality TV star. She’s considered one of the world’s most influential and powerful celebrities.

Given how much of her personal life is open to the public, even her measurements remain influential to other people. For this reason, I’m going to discuss Kourtney Kardashian’s bra size and its implications.

What Bra Size Is Kourtney Kardashian?

Kourtney Kardashian’s bra size is 34C. Her bust measures around 36 to 37 inches. She wears a bra with C cups and a band ranging from 30 to 32 inches.

She’s one cup smaller than her sister, Kim Kardashian, who wears a 34D bra. Still, Kourtney is considered the most body-positive of the Kardashians. She’s vocal about how it’s normal to have weight fluctuations due to medical conditions that can influence breast size and weight.

Her 34C breasts are common among women with hourglass and curvaceous bodies. This includes actress Leah Remini, who has a 34C bra size and a curvy physique. Kourtney Kardashian can also use 32D and 36B as sister sizes.

Kourtney Kardashian Measurements

Kourtney Kardashian is shorter in height, measuring in at 5 feet 0 inches (5′ 0”). It’s estimated that her body measurements are 34-26-39 inches, which translates to a bust size of 34″, a waist size of 26″, and a hip size of 39″. She weighs roughly 121 pounds.

Benefits of C Cup Breasts

Can Wear Tank Tops With a Built-in Bra

Due to the average size of C cups, a tank top that has a built-in bra is frequently available in this size. These types of tops also look best when you are a C cup, since you fully fill the shirt.

Can Keep Backless Bras in Position

Average-sized breasts give adhesive or stick-on bras enough breast tissue to stick onto without getting weighed down. Some women with smaller chests find backless bras difficult to keep up, because they don’t have enough breast tissue. Meanwhile, the absence of a back band may be too unsupportive for women with larger breasts.

Can Easily Fill Demi Cups

A demi bra perfectly suits mid-sized breast sizes. The right demi bra can cover the lower part of your breasts, creating a sexy neckline as the top of your boobs become fuller and rounder. Not only do you get great breast support with a demi-style bra, but you also add more volume to your bust!

Drawbacks of C Cup Breasts

Can’t Go Braless

C cups have prominent nipples and more breast tissue than A or B cups, so you might fail to go braless without drawing attention. It is also believed that breasts tend to sag when bras aren’t worn. Along with this, not having any support for your boobs might become painful if you are braless for long periods of time.

Possibility of Underarm Fat

Weight gain, genetics, and an ill-fitting bra can cause underarm fat. As your breasts get bigger, there’s also the possibility of forming side fat. This typically becomes more noticeable when your cup size is a C or bigger. When this happens, you might find yourself searching for bras that minimize side fat.

Might Attract Unwanted Attention

While C cups are average-sized, they are still pretty noticeable if you have a large band size or are shorter in height. This can make you feel slightly self-conscious as people take notice of your bust size and styling choices, especially if you are wearing tight clothing.
