Rachel Weisz is an English actress best known for playing righteous and smart characters. You may remember her from award-winning performances in The Constant Gardener, A Streetcar Named Desire, and The Favourite.

She is no stranger to losing weight and undergoing strict workout regimes when preparing for her roles, causing her bust to change. I’m going to discuss the bra size of Rachel Weisz, along with how weight can influence it.

What Bra Size Is Rachel Weisz?

The bra size of Rachel Weisz is 34C. This implies her overbust is in the 36-37-inch range. She must wear a bra with C cups and a band between 30 and 32 inches wide to support and shape the breast tissue.

She generally has an hourglass body, making her 34C breasts more prominent. Despite having the same band size as actress Famke Janssen, who wears a 34B bra, Weisz is one cup bigger and has a perkier silhouette.

Even as Rachel Weisz loses or gains weight for a role, there are minimal changes to the weight and shape of her breasts. Like fellow actress America Ferrera, who has a 34C bra size, and Danneel Ackles who has the exact size as well, Weisz can use 32D and 36B as sister sizes.

Rachel Weisz Measurements

Rachel Weisz is average in height, measuring in at 5 feet 7 inches (5′ 7”). I estimate that her body measurements are 37-24-35 inches, which translates to a bust size of 37″, a waist size of 24″, and a hip size of 35”. She weighs roughly 126 pounds.

Benefits of C Cup Breasts

Can Easily Fill Demi Cups

A demi bra perfectly suits mid-sized breast sizes. Demi bras 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 this style bra, but you also add more volume to your bust!

Bandeau Bras Stay In Place

Some bandeaus can make small breasts look flatter, while wearing one with large breasts may cause you to pull up the band constantly. You don’t need to worry about the absence of straps, because C cup boobs are big enough to keep bandeaus in place.

Ideal for Taping Breasts

Do you require some coverage and support, yet you’re wearing an outfit that won’t work with a normal bra? Boob tape can hold C sized boobs firmly in any position you like. This allows you to wear tricky tops without worrying about straps coming off the shoulders or cups showing through the neckline.

Drawbacks of C Cup Breasts

Can’t Go Braless

C cups have prominent nipples and more breast tissue than A or B cups, so going braless may not be the best option. Some bottom-heavy breasts may also sag. Along with this, not having any support for your boobs might become painful if you are braless for long periods of time.

Lack of Breast Separation

Some bras don’t offer breast separation. While this isn’t an issue when you have small boobs, women with C cups or bigger might not like these bras, because it can look like you only have one boob. This typically happens in attempts to make your breasts smaller or when wearing an unstructured bra.

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 help reduce visible underarm fat.
