Michelle Monaghan started as a magazine and catalog model before making her acting debut. She eventually landed notable roles in Kiss Kiss Bang Bang and the Mission Impossible films.

As she continues to take on more roles in television series, fans are interested in learning more about her. In this article, I will discuss the bra size of Michelle Monaghan, including the best styles for her size.

What Bra Size Is Michelle Monaghan?

Michelle Monaghan has a 32A bra size. This means she wears bras with A cups because she has an overbust size of 32 to 33 inches and a band size of 28 to 30 inches.

Because of Monaghan’s athletic-shaped breasts, there’s muscularity in the bust and a prominent space between the boobs. She won’t need to stretch out sports bras since there’s minimal breast tissue. The same applies to her Kiss Kiss Bang Bang co-star, Shannyn Sossamon, who also wears a 32A bra, and Keira Knightley, who also wears a 32B bra.

Michelle Monaghan can size up to 34AA or go down to 30B when experiencing gaping in the cups. American actress Jessica Stroup has a 30B bra size, so she and Monaghan are sister sizes in bras.

Michelle Monaghan Measurements

Michelle Monaghan is average in height, measuring in at 5 feet 7 inches (5′ 7”). I estimate that her body measurements are 33-24-33 inches, which translates to a bust size of 33″, a waist size of 24″, and a hip size of 33”. She weighs roughly 123 pounds.

Benefits of Small Boobs

Button-Down Shirts Fit

Let’s face it – button-down shirts are not made for women with large breasts unless you plan on sizing up 1-2 shirt sizes. Women with A-B cups don’t have to experience this struggle, since their boobs are not busting out of these shirts. You can easily wear your normal shirt size without it feeling too tight on your chest.

Can Go Braless

One of the best things about being small-chested is that if you don’t want to wear a bra, you don’t have to! At their core, bras are meant to support your boobs, and when you are an A or B cup, you don’t need a bra for this purpose.

Minimal Bounce During Workouts

One huge benefit of having small breasts is that they hardly affect athletic performance because of their lack of bounce. It can be painful to have your boobs bouncing around as you work out, and women with small chests don’t have to experience this pain. Plus, small boobs mean you can wear pretty much any sports bra style, even if it has minimal padding.

Drawbacks of Small Boobs

Sports Bras Can Flatten Breasts Too Much

Sports bras are a must-have in every woman’s wardrobe, even if you have small breasts. However, some sports bras have the potential to flatten your chest by compressing more breast tissue. It’s like watching your small breasts disappear once you wear a sports bra.

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.

Breasts Stay Small as You Gain Weight

If your breasts are dense with tissue, they won’t grow in size even as you gain weight. In turn, they may look significantly smaller as you gain more fat in other parts of your body. However, if you lose weight, the fat in your breasts may also reduce, causing your boobs to become even smaller.
