People remain curious about her fitness goals and body measurements despite the controversy surrounding her name. I’m going to explore the bra size of Samaire Armstrong and how it affects her body.

What Bra Size Is Samaire Armstrong?

Samaire Armstrong’s bra size is 30A. This means her overbust measures 30 to 31 inches, while her band ranges from 26 to 28 inches. These measurements are within the A cup range.

Her naturally thin figure and lack of curves make her 30A breasts less noticeable. The same applies to Canadian actor Elliot Page’s 30A bra size. It can be tricky to fill bra cups with this size, although Armstrong can use 28B and 32AA as alternatives.

A cups are smaller compared to B cups. Samaire Armstrong’s The O.C. co-star Rachel Bilson, who wears a 32B bra and actress Shantel Vansanten who also wears a 32B bra are one band and one cup size bigger than her.

Samaire Armstrong Measurements

Samaire Armstrong is average in height, measuring in at 5 feet 5 inches (5′ 5”). It’s estimated that her body measurements are 30-22-32 inches, which translates to a bust size of 30″, a waist size of 22″, and a hip size of 32”. She weighs roughly 119 pounds.

Benefits of Small Boobs

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.

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.

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.

Drawbacks of Small Boobs

Don’t Have Much Cleavage

A to B cup sizes don’t have prominent cleavage like larger breast sizes, even when wearing a plunging V-neck dress. In order to make it look like you have cleavage, you need to wear padded or push-up bras to make your bust look bigger.

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 most of the time.

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.
