Our boobs are wonderful 3D things and we all have a unique shape, so we don’t find using tape measures much use to find ‘your bra size’ - how could you measure a pint of milk with a ruler?! Instead, we prefer to arm you with knowledge because when you know what to look for, it’s easy to work out if a bra fits you well or not.

If you’ve got any questions, we’d love to help. You can call us (we’re open 7 days a week), chat to us via Live Chat or pop into our New York store for a bra fitting.

If your bra is riding up your back, the back size is probably too big! Try going down a back size and up a cup size (or two… or three!) until the back band is firm and your boobs are fully enclosed in the cups.

If your boobs are coming out at the bottom of your bra it’s a sign that your back band is too big. Your back band should be firm – so no room for under-spillage! Try a smaller back size and bigger cup size.

The underwire in your bra can hurt if it’s sitting on your breast tissue or armpit rather than your ribcage. If the underwire is sitting on your breast tissue, try a bigger cup size so that all your breast tissue is enclosed in the cups and if the wire is poking into your armpit try a smaller back size (but remember to go up a cup size to keep the volume in the cup size the same!).

If the centre of your bra doesn’t lay flat against your chest, it could be because the back band is too big (and not firm enough) or because the cups are too small, and your boobs are pushing the centre out. Try a bigger cup size and smaller back size.

The wires aren’t flat to your ribcage as there’s too much room in the back. Try a smaller back size.

REMEMBER this will change the cup size. Please see below…

If your boobs are spilling out of your bra, you need a bigger cup size. There should be a smooth line where the cups end with no bulging – even in a plunge style! You may need to try a smaller back size to keep the back band firm.

If your bra cups are wrinkling, this is a sign that there is too much room in the cups, so try a smaller cup size. This can also happen if you put your bras in the washing machine – so remember to hand wash your lingerie!

If you have gaps when your bra doesn’t sit flush on your boobs, the cups might be too big, so try a cup size smaller. If it’s a molded style (T-shirt bra) you’re wearing then the shape might not be quite right for you, so it might be worth trying a different style or a stretch lace style which will mold to your shape.

It’s not just about the letters and numbers written in your bra labels that dictate whether your bra fits you well. A big part of finding bras that fit you well is working out which shapes suit you best as each will do something different for you depending on your own individual shape. Check out our style guide for more information. We also have a range of bra accessories which can help to tweak the fit of your bra to give the perfect fit.

Sometimes your bras straps fall down simply because they’re too loose! (obvious, but true!), so try tightening the straps. You could also try a full cup style with more centred straps or a back converter which will turn your regular bra into a racer back to prevent straps from slipping off your shoulders.

Bra straps digging into shoulders can be a sign that your shoulders are taking the strain as the back band isn’t giving you enough support. Try a smaller back size or why not try bra strap pads which add a comfy layer and help to distribute the weight.

You’re not alone! Most of us have one boob bigger than the other. We suggest that you fit to your bigger boob or try a style with stretch lace that will mold to your shape.

So now you’re armed with the knowledge of how to work out if your bra is the perfect fit, but if you have any questions about how your bra should fit or would like any bra fitting advice, please get in touch as we love to help! You reach our friendly fitters on the phone, chat to us on our website, email us or visit one shops for a bra fitting any time – there’s no need to book!
