We’ve all seen the numbers. You’re scrolling through a fan wiki or a "body measurements" database, and there it is: a specific, confident-looking number for Alison Brie. Usually, it’s listed as a 32C. Sometimes a 34B. But if you’ve ever actually tried to buy a bra that fits, you know that these numbers are often just a guess—and usually a bad one.
Alison Brie is a powerhouse. Whether she’s playing the high-strung Annie Edison on Community or the fierce Ruth Wilder in GLOW, her physical presence is undeniable. But when it's about the technicality of her bra size, the internet is basically a game of telephone.
Honestly, the obsession with celebrity "stats" is kinda weird, but it does highlight a massive problem in how we talk about women’s bodies. We treat bra sizes like a fixed GPS coordinate, but for an athlete-actress like Brie, the reality is way more fluid.
The Problem With the "32C" Label
Most celebrity databases claim Alison Brie wears a 32C. Let’s break down why that’s probably not the whole story.
Bra sizing is a ratio, not a volume. A 32C means there is a 3-inch difference between the ribcage and the fullest part of the bust. However, most people—including many "experts"—don't realize that a 32C on a petite frame looks completely different than a 32C on someone taller.
Brie is about 5'3". She has a very lean, athletic build, especially after years of training for GLOW. In the world of professional bra fitting (like what you’d find at a boutique rather than a big-box mall store), someone with her frame would likely be fitted into a smaller band and a larger cup, perhaps a 30D or even a 28DD.
Why does this happen? Because the "standard" sizing most of us grew up with is outdated. It’s designed to fit as many people as possible into the fewest number of manufactured sizes. When you see Brie on a red carpet in a structured Versace or a vintage Dior gown, she isn't wearing an off-the-rack bra. She’s wearing a garment tailored to her exact, real-time proportions.
How Her Body Changed for GLOW
If you want to understand Alison Brie’s physique, you have to talk about her trainer, Jason Walsh. This wasn't just "celebrity cardio."
- Heavy Lifting: She ditched SoulCycle for deadlifts.
- Muscle Mass: She famously got to a point where she could do 40 pull-ups.
- Weight Gain: She openly talked about eating more to gain muscle.
When you gain that much muscle in your lats and back, your bra size changes. Your ribcage measurement (the band) often increases because of muscle density, even if your body fat stays low.
Basically, her "size" during Mad Men was likely very different from her "size" during the height of her wrestling training. Most online databases haven't updated their "facts" since 2012. It’s all a bit stagnant.
The Mental Side of the Tape Measure
Brie has been incredibly candid about her struggles with body dysmorphia. In a 2020 interview with Women's Health, she mentioned that she has "touch-and-go body issues."
This is where the fixating on numbers like "32C" becomes a bit harmful. She’s mentioned looking at old red carpet photos and thinking she looked "disgusting" at the time, only to realize years later that she looked beautiful. For her, fitness became a way to feel "powerful" rather than "skinny."

When we talk about her bra size, we’re often looking for a "perfection" that she herself has said felt like a prison.
Why You Shouldn't Use Celeb Sizes as a Guide
If you're looking up Alison Brie’s measurements because you think you have a similar body type, be careful.
- Vanity Sizing: A "B cup" at Victoria’s Secret is not the same as a "B cup" at a luxury brand like Agent Provocateur.
- Tailoring: Every dress she wears is pinned, tucked, and often has cups sewn directly into the fabric.
- Proportions: Height, shoulder width, and torso length all change how a bra size looks on a person.
Brie once told The New York Times that her line producer didn't think she could wrestle because she looked like a "little thing." But she was lifting 165 pounds. Strength doesn't always look the way we expect it to.
Real Insights for Finding Your Own Fit
If you’re trying to match the silhouette of someone like Alison Brie, stop looking at her supposed "32C" and start looking at your own ribcage.
Most women are wearing a band that is too large and a cup that is too small. If your bra band is sliding up your back, the 32 is too big for you—try a 30. If you have "spillover" on the sides, the cup is too small.
Don't get hung up on the letter. A "D" isn't huge; on a 30-inch band, it’s actually quite petite.
What to Do Next
Instead of trusting a random wiki for Alison Brie's bra size, take five minutes to do a "six-point" measurement on yourself. Use a soft tape measure and check your underbust (tight) and your full bust (leaning forward). Use a modern calculator like the one at the "A Bra That Fits" community on Reddit. It’s way more accurate than anything you’ll find in a celebrity gossip column.
Focus on how the garment supports your actual movement, especially if you’re active. Like Brie found during her GLOW years, the right support is about function and feeling like a "badass," not hitting a specific number on a tag.
