Ok, so what do all those letters mean? What’s a cup size? Here’s an easy guide to finding out your bra size:

The most reliable way to determine your size is to get fitted at a department store. It’s normally done free of charge (hurrah!)...just ask in their lingerie department.

Rather do it yourself? Ok, fab. Here’s how:

1. Using a measuring tape, determine the number of inches around your chest, just below your boobs.

2. Add 5 inches if it’s an odd number, and add 4 inches if it’s an even number. Voila! This is your bra measurement.

3. To find out what size cup you need, measure around the fullest part of your boobs.

• If the two numbers are the same, you need an AA-cup.

• If the two numbers differ by 1 inch, you need an A-cup.

• If the two numbers differ by 2 inches, you need a B-cup.

• If the two numbers differ by 3 inches, you need a C-cup.

• If the two numbers differ by 4 inches, you need a D-cup.

• If the two numbers differ by 5 inches, you need a DD-cup.

So, for example:

Let’s say your first measurement (around your chest, just below your boobs) is 28 inches. Adding 4 inches gives you 32 inches. That’s your bra measurement. Then let’s say your second measurement (around the fullest part of your boobs) is 34 inches. The difference between the two numbers (in this case, 32 and 34) is 2 inches, so you’d need a B-cup. Your right bra size would be 32B. Got it? Try it and see.
