Are you wearing the right bra size? Find out with our six tips!

Wearing the right bra is even more important if you have larger breasts. Without the right support, you could develop some uncomfortable side effects over time, such as poor posture. These six tips will help you determine whether you’re wearing the right size.

1. The back band

The back band is responsible for the majority of a bra's support – up to 80% in fact. Fasten your bra on the middle hook and see if you can fit three fingers under the clasp. If you can and if the band stays parallel to the floor, you've found the right band size! An easy way to check whether the band fits snugly is to lift your arms above your head. If your bra stays put, your band is tight enough. If it rides up, your band is too loose.

2. The underwire

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. The underwire should also encircle the breasts completely. Any poking or pinching is definitely a no-go.

3. The centre gore

The strip of fabric that connects the cups is called the centre gore. 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.

4. The cups

The fit of the cups determines the comfort and look of your bra. To find out if you're wearing the right cup size, check to see whether your entire breasts are inside the cups. If there’s any spillage on the top or the sides, try a larger cup size with the same band size. If the cups are gaping or wrinkling, try a smaller cup size or a different bra style.

5. 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.

6. 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.

During fittings, we noticed that our PrimaDonna Twist styles have a slightly smaller fit than our PrimaDonna styles.

  • If you know your PrimaDonna size and you find a PrimaDonna Twist look you love, try going up a cup size.
  • If you usually buy PrimaDonna Twist and you find a PrimaDonna look you love, go down a cup size. In both cases, stick to your usual band size.
  • New to PrimaDonna and PrimaDonna Twist? For PrimaDonna twist we recommend choosing your usual bra size. For PrimaDonna we suggest going down a cup size and choosing the band size you usually wear.
