How to check and correct your Bra Size

Step 1: Check and correct your Bra Band size

Most women wearing the wrong Bra size are wearing the wrong Band size, in most cases, too big. Many start wearing 36DD and then fit perfectly into a 32FF or 32G after a professional fitting.

Standard UK Bra Band Sizes move in 2-inch increments from 28 to 46, a broad spectrum of sizes covering women of all sizes!

Tell-tale signs that your Bra Band size is too big.

If you have any of the above issues with your current Bra size, move one Band size lower to get a firmer fit on your band. For example, move to 34 from 36. Move another Band size lower if you tend to wear new Bras on the tightest hook.

It's important to review your Band size as your weight fluctuates to ensure you get maximum support.

Step 2: Change your Bra Cup Size

Once you have fixed your Band size, you will need to find a Cup size that can contain the entire volume of your breasts without spillage. Standard UK Cup sizes follow the sequence below; you will notice that Cup size I and Cup size EE do not exist:


The Cup size on its own does not represent your breast size. The breast size is a combination of the Band and Cup size. For example, a 36D Bra will not fit the same breast size as a 34D.

When moving to a smaller Band size, increase a Cup size to get the same breast volume. For example, a 36D would fit the same breast size as a 34DD. These are commonly referred to as "Bra Sister Sizes".

- If you moved to a smaller Band size in Step 1, increase by one Cup size to fit your breast size. For example, if you started as a 36DD, you become a 34E.

- If you were slight experiencing spillage on your original Bra, increase your new Cup size once more to ensure the entire volume of your breasts fits into the Cup. For example, the 34E now becomes a 34F. 

We use this method consistently, which works better than the measuring tape method; because it involves listening to what your current Bra is telling you! Everyone's body is different, and that's the beauty of listening to your own body.
