Does Your Bra Really Fit? Let’s Find Out

If you’re like most women, you’ve probably wondered at some point, “Am I actually wearing the right bra size?” Maybe you’ve measured yourself, tried on a few different sizes in-store, and still walked away unsure. You’re not alone. In this post, we’ll walk through how to tell if your bra truly fits—and what to do if it doesn’t. Let’s dive in.

First things first: don’t feel discouraged if you suspect you’re in the wrong size. In our experience, over 90% of women are not wearing their ideal fit. Many of us also wear the same bra size year after year—even though our bodies naturally change over time.

Instead of focusing too much on the number and letter on the tag, let’s shift our attention to how your bra fits. Start by putting on the bra you feel fits you best. Adjust the straps and band, then we’ll check a few key fit points together.

Fit Point #1: The Cup

Look at the center of your bra, between your breasts.  For a perfect fit, the centre gore should lie flat against the chest. If it doesn’t and if the underwire lifts away from the body, either size up or try a different bra style that better suits the shape of your breasts.  If it’s pulling away from your body, your cups are likely too small—especially if you’re seeing spillage or the dreaded “double-boob.” On the flip side, if the cups look wrinkled or empty, they may be too large.

Fit Point #2: The Underwire

Turn sideways in the mirror and see where the underwire ends. The wire should sit just behind your breast tissue, not on it—and definitely not cutting in under your arms. An underwire that’s too far back is just as problematic as one that’s too short.  The underwire should lie flat against your chest, without digging in. If it bounces back when you press on it, the cups are probably too small. Any poking or pinching is definitely a no-go.

Fit Point #3: The Band

Your band should provide about 90% of your support, with straps making up the remaining 10%. Think of the band as a “snug hug” around the lower part of your back. When it fits properly, it stays in place and doesn’t ride up—helping your bra stay supportive and comfortable all day long. The band should sit parallel to the floor. It shouldn’t be too loose or too tight. If you can fit three fingers between the band and your back and if your breasts stay put when you raise your arms, you've found the right band size.

Fit Point #4: The Straps

Did you know that bra straps only account for about 10% of your support? The back band and the centre gore do most of the heavy lifting when it comes to support. Adjust the straps until you can fit two fingers between the strap and your shoulder.  The straps should fit comfortably and shouldn't dig into your shoulders or slip off.

Fit Point #5: How Does it Feel???

The final and most important check: how does your bra feel? Even if you’ve found the perfect size, how a bra feels is the most important test. You may feel more comfortable in a bra with more coverage or in a more revealing style made from lighter materials.

After checking these fit points, you should have a better sense of whether your bra is working for you or needs improvement. Keep in mind that bra fit can be tricky—every brand fits a little differently. Some have deeper cups, others run shallow. Bands can be firm or forgiving.

That’s why your best next step is often a visit for a complimentary fitting.  Our trained fitters understand how different brands and styles work and can guide you to a bra you’ll feel great wearing.
