Megan Fox is an American actress and model who rose to fame with the Transformers films. She eventually starred in Confessions of a Teenage Drama Queen, Jennifer’s Body, and Teenage Mutant Ninja Turtles.

She is known for her clothing choices that highlight her breasts, which the media attributed to her choice of bra size. I’m clarifying the bra size of Megan Fox and how she achieves a lifted look.

What Bra Size Is Megan Fox?

Megan Fox’s bra size is 34B. Her bust measures around 35 to 36 inches, whereas the band ranges from 30 to 32 inches, making her a B cup.

Megan Fox Measurements

Megan Denise Fox’s measurements come in at:

  • Height: 5 foot 4 inches (5′ 4″)
  • Weight: 122 pounds (122 lbs)

She  has 34-22-32 inch measurements and was born on May 16th, 1986, making her a Taurus.

She uses balconette, demi, and plunge bras to have rounder, fuller breasts. Her 34B breasts are common among actresses with slim and hourglass figures. For example, fellow actress Gina Rodriguez has a 34B bra size that complements her narrow waist and curvy hips.

Megan Fox can size down to 32C if the band is too tight or go up to 36A when her breast tissue can’t fill cups. This means she shares almost similar bust proportions to actress Jennifer Lawrence, who wears a 32C bra.

Benefits of a Small Chest

Don’t Have Side Boobs

If you love wearing tank tops with bras, 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 wearing bras that will hide your dreaded side fat. You can wear anything without thinking about side boobs or bulges.

Don’t Have Back Pain

Ladies blessed with small breasts can avoid the dreaded back pain. Breast weight can cause your shoulders to move forward, which forces the muscles in your back and shoulder blades to adjust. Having less weight in front means your torso can easily carry your breasts, and the weight doesn’t need to be redistributed.

Can Easily Wear Low Cut Shirts

Women with smaller boobs can get away with wearing low cut tops and dresses without them looking too risque. Even if you are dancing or jumping around, your boobs won’t fall off your bras while wearing a wrap dress, a scoop-neck tank top, or a V-neck camisole.

Drawbacks of a Small Chest

Gaps Form Between Your Boobs and the Bra

When you have A-B sized breasts, it’s not uncommon for a gap to form between your chest and the bra you’re wearing. This is because your boobs are not large enough to fill the bra. Even if you try sizing down to a smaller bra, you might experience this issue.

Have a Less of a Figure

Small breasts can give your physique a straight, slim appearance. If your shoulders and hips are the same width, having a flat chest can also make you feel shapeless. Because of this, you might find yourself gravitating towards wearing push up bras made for small breasts most of the time.

Might Feel Self Conscious

It’s normal to feel self-conscious about having small breasts, particularly if you truly want to have large boobs. This can sometimes make you focus on looking for bras that can volumize your breasts regardless of the fit. However, small breasts can be as sexy as other breast sizes.
