Bra Calculator

We know how tricky finding the right bra size can be, which is why we've created our bra calculator. Just answer a few quick questions about your current bra size and we'll do the rest.

Your perfect fit is just a few clicks away…

Before you start

Check what your bra size is and choose the sizing option that applies to you. For the most accurate results, put on your best fitting bra - preferably an underwired and non-padded bra. Make sure you’re not wearing a moulded t-shirt bra.

Guidelines for brand sizing

British Brands

Freya, Fantasie, Just Peachy, Panache, Charnos, Lepel

As we are a UK company, we consider this to be 'True to size' and this fitting tool assumes that you have started your journey in a UK brand.

Designer brands

Elle MacPherson, Stella McCartney, Princesse Tam Tam

Designer brands have a tendency to be a size smaller in the cup than standard UK sizing.

French/European Brands

Chantelle, Aubade, Simone Perele, Lejaby

These brands also have a tendency to come up slightly smaller in the cup. In Europe, they do not have a DD cup, as we do in the UK and they will call this an E cup. You will see a pop-up, when selecting product on our site, which will advise you of this before completing your purchase. .

American Brands

Wacoal, Calvin Klein

American brands also have their own sizing system, this means that their sizing runs up to an N cup, but this is equivalent to a UK K cup. You will see a pop-up, when selecting product on our site, which will advise you of this before completing your purchase.

  1. How does your underband look at the back?

    1. It's Riding Up

      The underband is arching in an upside down U shape.

    2. It's Riding Down

      The underband is sitting too far down the body.

    3. It Sits Straight

      The underband is sitting in a parallel line around the body.

    4. It's digging in

      The underband is digging into the skin and leaving slight red marks.

    5. It's breaking the skin

      The underband is digging in enough that it will cause discomfort and mark the skin.

    Fastened on the loosest hook, how far can you comfortably stretch your underband out?

    1. 0-4cm

      You can stretch the underband out up to 4cm.

    2. 5-8cm

      You can stretch the underband out up to 8cm.

    3. 9-12cm

      You can stretch the underband out up to 12cm.

    4. 13-16cm

      You can stretch the underband out up to 16cm.

    5. 17+cm

      You can stretch the underband out 17cm.

  2. How do the wires look at the centre front of your bra?

    1. They Sit Flat

      The wires are sitting flat against the body with no room to fit your fingers in the gap.

    2. There is a Gap

      The wires are sitting away from the body and there is a gap between the wires and the rib cage.

    3. They Dig In

      The wires are digging in and causing pain or discomfort at the centre front or side of the cup.

    Try a different style of bra if the wires dig in at the centre front, this is the wrong bra for you
  3. Is there any bulging at the top of your cups?

    1. Yes

      The breasts are bulging at the top of the cups.

    2. No

      The cups have fully encapsulated the breasts.

  4. Can you pinch any excess fabric on the neckline edge of your cups?

    1. Yes

      The cups are loose and you can pinch excess fabric.

    2. No

      The cups lie flat against the bust with no digging in.

    Can you pinch any excess fabric at the top of the cups?

    1. 0.5-1cm

      You can pinch up to 1cm.

    2. 1-1.5cm
