Known for her fun fashion style and cheerful personality, people remain curious about her bust measurements. I’m going to talk about Isla Fisher’s bra size and the best bra styles for it.

What Bra Size Is Isla Fisher?

Isla Fisher has a bra size of 34C. This suggests her overbust measures around 36 to 37 inches. She needs to wear bras with C cups and bands ranging from 30 to 32 inches.

Her breasts have a round shape, which makes her 34C breasts more prominent. In comparison, Fisher’s The Great Gatsby co-star Carey Mulligan has a 32B bra size, making her bust smaller since she has a slim physique.

Similar to Drew Barrymore who also wears a 34C bra, Isla Fisher can use 32D and 36B as sister sizes for her 34C bra. She can share bra styles with American actress Amanda Seyfried, who wears a 32D bra. For these sizes, it’s best to wear plunge or demi bras to contour the breasts and make the bust look fuller.

Isla Fisher Measurements

Isla Fisher is shorter in height, measuring in at 5 feet 3 inches (5′ 3”). It’s estimated that her body measurements are 34-24-35 inches, which translates to a bust size of 34″, a waist size of 24″, and a hip size of 35″. She weighs roughly 126 pounds.

Benefits of C Cup Boobs

Can Wear Sleep Bras Comfortably

Regardless of your sleeping posture, it’s ideal to use a sleep bra if you notice your breasts shifting to the side. With a C cup size, you won’t have large enough breasts to feel too restricted by the cups as you sleep.

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.

Can Wear Tank Tops With a Built-in Bra

Due to the average size of C cups, a tank top or camisole with 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.

Drawbacks of C Cup Boobs

May Look Smaller on Women With Bigger Hips

Women with bigger hips or pear shaped figures might feel that their C cup chest is too small. Even though they have mid-sized boobs, their chest can be overshadowed by having wider hips. However, you can solve this by wearing a padded push-up bra or tops with bold colors to draw more attention to the top half of your body.

Might Need to Wear Underwired Bras

You might need to use an underwire bra for overall support in lifting and shaping your breasts. While some bras have flexible or cushioned wires, it’s undeniable that wired bras can be troublesome, especially if you feel them digging into your ribcage.

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.
