Is My Cup or Underband Too Small on My Bra Size? – Use This 1 Trick

Finding the right bra size can be tricky. Many women struggle to figure out whether the discomfort they’re experiencing is due to their cup size or underband being too small. If you're dealing with a bra that just doesn't feel right, how do you know which part is causing the issue?

Here’s a simple trick you can use to quickly identify the problem—and it's a game-changer!

The Upside-Down Bra Trick

One of the easiest and most effective ways to determine if your underband or cup size is too small is by using what I call the Upside-Down Bra Trick. Here's how to do it:

1. Turn Your Bra Upside Down: Take your bra and flip it upside down, so the cups are hanging below the band.

2. Put It On Backwards: Fasten the bra as you normally would, but don’t put your arms through the straps or your breasts into the cups.

3. Assess the Fit of the Band: With the cups out of the way, you can now focus solely on the fit of the underband. It should feel snug and secure, without being too tight or riding up.

This trick isolates the underband from the cups, making it easier to tell if the band is too tight, too loose, or just right. If the band feels too restrictive or uncomfortable, it’s a sign that you need to go up a band size. Conversely, if it feels loose, try a smaller band size.

Why the Underband Fit is So Important

The underband is the foundation of your bra’s support. It should sit firmly around your ribcage without riding up or digging in. If your underband is too loose, the cups won’t be able to provide the right support, and if it’s too tight, it can cause discomfort and restrict your movement.

At MAAREE, we recommend starting with a snug underband that feels secure but comfortable. Our Solidarity Bra comes in underband and cup sizes separated, rather than Small/ Medium/Large to offer a more tailored fit for you to get your perfect support.

Other Tips to Identify Bra Fit Issues

While the Upside-Down Bra Trick is a fantastic tool, there are a few other ways to figure out if your cup or underband size needs adjusting:

1. Check for Band Riding Up: If your bra’s band is riding up at the back, it’s a clear sign that the band is too loose. Try a smaller band size.

2. Cup Spillage: If your breasts are spilling over the top or sides of the cups, the cups are likely too small. Go up a cup size for a better fit.

3. Gapping Cups: On the other hand, if there’s a gap between your breasts and the cups, your cups may be too large. Try a smaller cup size.

4. Strap Tightness: Your straps should provide gentle support but shouldn’t be doing all the work. If your straps are digging in, it’s often a sign that the band is too loose and you’re compensating by tightening the straps too much.

Why It’s Worth Finding the Right Fit

Wearing the right bra size isn’t just about comfort—it’s essential for your health and wellbeing. An ill-fitting bra can cause discomfort, chafing, and even back or shoulder pain. Taking the time to find your perfect fit can make a world of difference in how you feel and perform during your workouts.
