Make a bra you already love fit again

Bodies change with the seasons, with pregnancy, with hormones and with time, and a band that suddenly digs in does not mean it is time to start again. A bra extender adds gentle room across the back so a favourite bra feels right once more.

Ours come in 2 hook, 3 hook and 4 hook widths to match your bra, and add up to 5cm of breathing space. They are made from strong, durable polyester rather than thin elastic, so they hold their shape and will not snag delicate lingerie. If it is shape rather than fit you are after, see our bra inserts.

Which extender, and which fix you actually need

Match the extender to your bra and your outfit:

  • A two hook band needs a 2 hook extender, a three hook band a 3 hook, and so on.
  • For a low back dress, reach for our Low Back Bra Extender, which drops the strap right down.
  • Bra Clips pull straps into a racerback or hide them, Strap Cushions stop shoulder straps biting, and Clear Straps give discreet support under sheer tops.

No sewing required, just hook in and go. If you are not sure an extender is the answer, our guide on when do you need bra extenders helps you decide.

How Do You Use a Bra Extender?

It really is as easy as hook, extend and go. Match your bra extender to your bra's hook size (2 hook, 3 hook or 4 hook), hook it into the existing eyes on your band, then fasten your bra as usual using the extender's hooks. No sewing, no stress, just a bit of extra room exactly where you need it. See the difference it makes in how a simple bra extender can completely change your outfit game.

Why Would You Use a Bra Extender?

Bra extenders are brilliant when your bra is just that little bit too tight but otherwise fits beautifully. They are a lifesaver through pregnancy, weight changes, or those times of the month when everything feels a bit squishy. Rather than buying a whole new set of bras, you can adjust the ones you love, a clever little wardrobe hack that helps them work harder for longer. For more, read when do you need bra extenders.

Can you use bra extenders more than once?

Yes, our bra extenders are completely reusable and made to last through hundreds of wears, which is especially handy when your body or bra fit fluctuates. As long as you are gentle with them and keep them out of the rough wash cycle, they will keep doing their thing for ages. A small investment with a big payoff in comfort. Explore our reusable styles in the bra strap extenders collection.

How do you use a bra extender?

Using a bra extender is wonderfully simple, no sewing skills required. Just attach the hooks of the extender to the existing eyes on your bra band, then fasten your bra as usual using the extender's hooks. It adds extra length around the back to relieve pressure and give you that bit of breathing room when your bra feels snug. For styling ideas, see how a simple bra extender can completely change your outfit game.

Will bra extenders damage my bras?

Not at all. A good quality bra extender like ours is designed to be gentle on your lingerie. Unlike elastic styles, our premium polyester version does not pull or stretch, it simply adds an extension to the band without interfering with the structure. Because you are no longer forcing a tight bra to fit, you are actually protecting it by easing the strain on the hooks and fabric.

Can I use a bra extender with any bra?

Yes, any standard bra with a hook and eye closure works with our Secret Weapons bra extenders. You will just need to match the extender to the number of hooks on your bra, typically a 2 hook, 3 hook or 4 hook. They are made for traditional bras, so they are less suited to seamless or sports bras without hook closures. Our guide on when do you need bra extenders helps you match one to your bra.

Are they washable?

Yes, definitely, just be kind to them. Hand wash your bra extenders in warm, soapy water and lay them flat to dry, steering clear of the washing machine and harsh detergents that could shorten their life. Look after your extenders and they will keep looking after you. Browse our durable, easy care styles in the bra strap extenders collection.

What's the difference between a bra extender and a low-back bra extender?

A standard bra extender adds extra length across the band, while a low back extender is designed to pull your band down lower across your back, perfect for low back dresses and tops. It redistributes the tension to sit lower while still giving you the coverage and support you need. For low back looks, see our low-back bra extender for low-back dresses.
