Common questions

Can a strapless bra really support a large bust?

Yes. A well-designed strapless bra can provide excellent support for a larger bust.

The key is getting the band and cups right. Without shoulder straps, the band needs to do most of the supporting work.

Look for structured cups, a firm band and plenty of coverage around the sides. Most importantly, choose a bra designed for your cup and band size.

Our Determine Your Size guide can help you check your current size.

How do I stop a strapless bra from falling down?

Start with the band. If it's too loose, your strapless bra is more likely to slide down.

The cups also need to fit correctly. Cups that are too small or the wrong shape can push the bra away from your body.

Features such as wider bands, supportive side panels and silicone grip strips can also help keep everything securely in place.

If you're constantly pulling your bra up, it's worth checking your size with our Determine Your Size guide.

How should a strapless bra fit a large bust?

A strapless bra should feel firm and secure without being painfully tight.

The band should sit level around your body and stay in place when you move. Your breasts should sit completely inside the cups without spilling or excessive gaping.

The centre of an underwired strapless bra should also sit comfortably against your body.

Our How Should a Bra Fit? guide explains the main signs of a good fit.

Should I size down in a strapless bra for a large bust?

Don't automatically size down just to make your strapless bra feel tighter.

A smaller band may feel more secure initially, but it can become uncomfortable. It may also affect how the cups and underwires sit.

Start with your correctly fitted bra size and then assess the individual style. The band should feel firm enough to stay in place without digging into your body.

Our Bra Fit Hub has more advice about finding a comfortable, supportive fit.

What features should I look for in a strapless bra for a large bust?

Look for a firm band, structured cups and good coverage around the sides and back.

Underwires can provide extra structure and separation, while wider wings can help create a more secure base. Silicone grips may also help reduce slipping.

Convertible straps are useful if you want more ways to wear your bra with different outfits.

Your breast shape matters too. Our Breast Shape Guide can help you understand which bra shapes may suit you.
