    How to put on your bra

    Follow these four steps when trying on your bra to make sure it fits perfectly and comfortably.

    1. Lean Forwards

    This will allow your breasts to fall naturally into the bra cups and gives the best support.

    2. Lift Wires

    As you straighten up, lift the wires up into the crease of your bust before fastening the bra.

    3. Lift In

    This will give you a good idea of how comfortable the bra is and how well it fits.

    4. Adjust Straps

    Adjust your shoulder straps to ensure you get the right support.

    Check your bra size

    Are you wearing the right size?
    Try on your best fitting bra, stand in front of a large mirror and follow these steps to find out...

    Start with the Underband...
    1. Your underband should be nice and snug when fastened on the loosest hook. You shouldn't be able to pull it more than two inches away from your back.

    2. The underband should sit horizontally level across your body, in line with the wires at the front.

    3. The length of your straps should be adjusted enough to support the cup, but should also feel comfortable.

    ...Now move onto the cups!
    1. There should be no bulging or gaping at the top of the cups.

    2. The wire should completely enclose each breast, sit right in the crease underneath your breasts, and finish under your arms.

    3. The wire should sit flat against your rib cage, from the middle of your chest and along the crease of your bust, with absolutely no lifting away.

    Try a smaller back size

    If your underband rides up (red line) it's too big. It should sit horizontally level across your back (green line). Test this by pulling it away from your body - it shouldn't stretch more than two inches.

    Try a smaller back size

    Your underband should provide most of the support, so if your straps are digging in it's a sign that the back size is too big.

    Try a bigger cup size

    If your cup size is too small, your bust will bulge over the top and sides. The top of the cup should lie totally flat on your bust. If in doubt, try on a t-shirt over your bra, as this will make any bulging more obvious.

    Try a bigger cup size

    The bra wire should sit behind your breast, not on it. If your bra fits correctly the wire will encase the bust completely and not dig in uncomfortably.

    Try a bigger cup size

    If the wires lift away from your body in the middle, or are sitting on top of your breast at all, then your cup size is too small.

    Try a smaller cup size

    Your bra should fit perfectly without any gaps. If there is space in the cups around your bust, then the cup is too big.


    For every back size you go down, we recommend you go up a cup size and vice versa. For example, if you were wearing a 38C, but you want to try a 36, we'd suggest you go up a cup and try a 36D.

    How to care for your bra

    Care for your bra properly and it will last and last.

    Unless specified differently on the garment's wash care label...

    • Always try to hand wash your bras and never put them in the dryer - this will reduce elasticity and cause them to shrink.

    • Wash your bras in cool water with a delicates detergent. Don't wring them out, just let them drip dry, and don't put them on a radiator where the heat can damage them.

    We suggest that you buy a new bra every six months - as the best support your bra gives you is within the first six months.
