How do I know my bra size?

To determine your bra size, you’ll need to measure your band size and bust size. You can do this at home using a soft measuring tape.

  1. Measure your band size: Wrap the measuring tape around your ribcage, just under your bust. Make sure the tape is snug and parallel to the ground. Round the number up to the nearest whole number.
  2. Measure your bust size: Wrap the measuring tape around the fullest part of your bust, making sure the tape is snug but not tight. Round the number up to the nearest whole number.
  3. Calculate your cup size: Subtract your band size from your bust measurement and use the difference to find your cup size on the chart below.

Calculate your cup size

Once you have your band size and bust size, you can use them to calculate your cup size using the following formula:

Bust size – Band size = Cup size

For example, if your band size is 32 inches and your bust size is 36 inches, your cup size would be D (since 36 – 32 = 4).

What if I’m between sizes?

If you find that you’re between two cup sizes, try both sizes on and see which one fits better. Keep in mind that different brands and styles may fit differently, so you may need to adjust your size accordingly.

Can cup sizes vary by brand?

Yes, cup sizes can vary by brand and even by style within the same brand. It’s always best to try on multiple sizes and styles to find the best fit for your body.

Can my bra size change?

Yes, your bra size can change due to weight fluctuations, hormonal changes, and pregnancy. It’s important to regularly measure yourself and reassess your bra size to ensure that you’re wearing a bra that fits properly.

What if I can’t find my size?

If you can’t find your size in stores or online, consider looking for specialty bra stores or having a bra custom-made for you. Many bra brands also offer extended sizing options, so be sure to check their websites or contact customer service for more information.

Conclusion

Now that you know what all the bra cup sizes available are, you can confidently shop for bras that fit your body. Remember to measure yourself regularly and try on multiple sizes and styles to find the perfect fit. A well-fitting bra can make all the difference in your comfort and confidence.
