Mariah Carey is a singer, songwriter, and producer who has been in the industry since the 1980s. She has record-breaking albums and tours, making her one of the top-selling artists in America.

She’s also known for wearing risque outfits, whether it’s for concerts or everyday wear. I’m going to talk about Mariah Carey’s bra size in this context and how it affects her life and career.

What Bra Size Is Mariah Carey?

Mariah Carey’s bra size is 34D. Her heavy bust measures around 37 to 38 inches. She needs to wear a bra with D cups and a band ranging from 30 to 32 inches to lift and shape her breast tissue.

This is among the most common sizes for women with hourglass and curvy bodies. She comfortably shows off her bust, whether in a bralette for large breasts or a cage bra. The struggle is that she risks bra side spillage and nipples peeking through her tops.

Mariah Carey can use 32DD and 36C as sister sizes. For comparison, actress Hayley Atwell has a 32DD bra size, whereas actress Jessica Biel wears a 36C bra.

Mariah Carey Measurements

Mariah Carey is taller in height, measuring in at 5 feet 9 inches (5′ 9”). It’s estimated that her body measurements are 37-25-35 inches, which translates to a bust size of 37″, a waist size of 25″, and a hip size of 35”. She weighs roughly 145 pounds.

Benefits of Large Breasts

Deep V Tops are Ideal for Large Chests

Let’s face it – tops and dresses with deep v necklines were made for women with big breasts! These tops can often plunge too much on smaller breasts, and the fit can be awkward. Plunging necklines work best with taped breasts that are at least a D cup.

Flattering Bust in Corsets

A corset is worth having if you want to accentuate your assets while narrowing the waist. It’s a snug-fitting garment that can control 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.

Get More Body Warmth

Adipose tissue (AKA body fat) provides the fat that promotes breast development and maturation. To keep the body’s temperature stable, it also stores extra energy and calories that can generate heat. So, what does all this mean in simplified terms? Larger cups contain more body heat, which is advantageous on chilly days!

Drawbacks of Large Breasts

Inevitable Uni-Boob Look

Large breasts can develop a “uni-boob look” when wearing an unstructured bra without underwire. Since there is no structured center gore to help separate the breasts, a uni-boob can also happen when you are wearing your durable sports bra for running with large breasts. Lack of support from the cups, straps, and bands can also restrict the breast tissue rather than lift it.

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.

Can be Difficult to Sleep on Your Stomach

Forget about sleeping on your stomach or lying face down to sunbathe. Attempting to do so will only smash your breasts and make you uncomfortable if you do this for a long period of time. Unless you put a pillow on your hips, sleeping in this position will only apply unnecessary pressure to the chest.
