Slow Fashion

Slow fashion is becoming more and more popular in the UK, as people seek out sustainable clothing options. As the demand for ethical and sustainable fashion has grown, so has the need for accurate bra sizing. Our free online bra size calculator is the ideal tool for finding the right fit for both comfort and style.

Finding the right bra size can be a tricky business. Getting the right fit is essential to avoid discomfort and potential skin damage. With our free online bra size calculator, you can easily measure your bra size and find the perfect fit for you.

To use our bra size calculator, measure the fullest part of your bust to determine your band size. To measure your bust size, use a measuring tape around your chest and make sure it is snug, but not tight. Once you have your bust size, you can use it to calculate your band size. For the most accurate results, measure your bust size with the bra size calculator twice and use the average measurement.

Calculate Bra Size

Once you have your band size, you can use the bra size calculator to calculate your cup size. To do this, measure around the fullest part of your bust and subtract your band size from this measurement. This will give you your cup size, which you can use to find the perfect fit for you.

Remember that different brands have varying sizing standards, so the same cup size can vary between brands. Make sure you get the right fit by measuring your bust size with our bra size calculator. Wearing the wrong size bra can cause red marks, irritation, and discomfort, so it’s essential to get the right fit.
