UK and US bra band sizes (32, 34, 36) are broadly similar, but cup letters diverge at larger sizes, which is why your usual size can feel different between brands. The reliable approach is to measure your band and bust, then check the specific size guide on the product you're buying rather than assuming a letter. Here's how the systems compare.
How do you find your bra size before converting?
Measure two numbers first: your band (under the bust) and your bust (across the fullest part). Our complete bra size guide walks you through measuring at home in minutes.
How do band sizes compare across UK, US and Pakistan?
Band sizes are based on your ribcage measurement, and UK and US band numbers (32, 34, 36 and so on) are broadly similar. Pakistani retailers typically use UK or US sizing, so the band is the easier part to match across systems.
How do cup sizes differ between UK and US?
Cup sizing is where systems diverge. A, B, C and D cups start out similar, but the larger cup letters differ between UK and US systems. This is why checking each product's specific size guide matters more than assuming your usual letter.
What's the most reliable way to get the right size online?
Measure yourself accurately, then check the size guide on the actual product. At Erblis, each product page includes sizing details so you can match to your measurements directly rather than relying on conversions.
Can your bra size change over time?
Yes. Weight changes and even a worn-out band can shift your fit, so re-measure periodically — see how often to replace your bras. The same measure-then-check approach applies to underwear sizing.
