Why is the Correct Bra Size Important?

Wearing the wrong bra size can cause a whole bunch of issues. It can lead to discomfort, poor posture, and even health issues like back pain. On top of that, it can make your clothes look less flattering. So, getting the right size is not just about comfort; it’s about feeling and looking your best.

How to Measure Your Bra Size?

Step 1: Measure Your Band Size

Wrap a measuring tape around your ribcage, right under your bust. Make sure it’s snug but not too tight. This is your band size.

Step 2: Measure Your Bust Size

Next, measure around the fullest part of your bust. Make sure the measuring tape is level all the way around.

Step 3: Calculate Your Cup Size

Subtract your band size from your bust size. The difference will help you find your cup size based on standard sizing charts.
