Celebrities with Bra Cup Size A Measurements

Sam Adamson

Cup size A might be the most common bra size in Hollywood and high fashion, and it’s also the most misunderstood. The letter describes proportion, not size. An A cup means the bust measures about one inch more than the band. A 32A and a 34A belong to different frames, and neither has anything to do with height, weight, or build.

This list compiles female celebrities reported to wear an A cup, with band size and bust measurements for each. Every name links to a full profile with complete measurements.

As always, these are reported estimates. Celebrities rarely confirm bra sizes on record, so treat each figure as a well-researched approximation rather than an official number.

You’ll see sizes like 33A or 35A reported for some celebrities here and across the web. Bras are only sold in even band sizes, so an odd-numbered figure usually means someone published a raw underbust measurement rather than a purchasable bra size. A reported 33A generally means the wearer buys a 32 or 34 depending on fit preference. We keep the reported figure for accuracy, but read odd bands with that in mind.

What about cup size AA?

AA sits one step below A, with the bust measuring roughly half an inch to an inch over the band. It’s a real size, but you’ll rarely see it reported for a celebrity, as media coverage often rounds everything small up to A.

That’s why this page doesn’t carry a separate AA table. The handful of celebrities occasionally reported as AA, including Keira Knightley and Kate Moss, are listed under A above because that’s the figure that appears most consistently.

For readers checking their own size: if your bust and band measurements are less than an inch apart, AA will usually fit better than A.

Sister sizes:

The same cup volume exists across multiple labeled sizes. Going up a band and down a cup keeps the volume roughly constant, which is why an A cup on one band can match a B on a smaller one.

Bra Size	Bust	Same cup volume as
30A	31 in / 79 cm	32AA
32A	33 in / 84 cm	30B, 34AA
34A	35 in / 89 cm	32B, 36AA

Frequently Asked Questions:

What does bra cup size A mean?

An A cup means the bust measures about one inch more than the band. A 32A is a 33-inch bust and a 34A is a 35-inch bust.

Is cup size A common among celebrities?

It’s arguably the most common cup size in fashion modeling, and it appears constantly among actresses, singers, and athletes.

What is the difference between A and AA?

About half an inch to an inch of bust over the same band.

Does cup size A mean a small body frame?

Cup size says nothing about height, weight, or build. This list includes athletes, tall runway models, and petite singers who all share the same cup size on very different frames.

Why do some celebrities have odd sizes like 33A?

Bras are only sold in even band sizes, so odd numbers usually mean a raw underbust measurement was published as a bra size.

Can a celebrity’s cup size change over time?

Yes, it does. Weight changes, pregnancy, fitness, and age all shift measurements.

Is bra cup size the same as bust size?

No. Bust size is a measurement around the fullest part of the chest. Cup size is calculated from the difference between the bust and the band.
