Does such a thing as the best strapless bra exist? I can't count the number of times I've sworn them off after spending an embarrassing evening hoisting them up. But when you want to wear your favourite bandeau dress—one of the biggest dress trends for summer 2025—, what are the options? Now, you could just go braless, but if you're not exactly small-chested, this can pose a problem, not to mention it can leave you with quite the backache. So thanks to the abundance of shoulder-baring shirts like halter-neck tops, cami dresses and low-back options dropping in, I decided to go on a mission to find a decent strapless bra that fits well and stays put.

To help me, and you, find the best strapless bras and ensure they fit properly, I spoke to lingerie expert Eloise Rigby, who owns The Pantry Underwear, which caters to cups from A to K. She gave me a few helpful rules to stick to, which I've handily spelled out below.

1. Go for One Back Size Smaller Than Usual.

Without shoulder straps, cups are only supported by the back strap, so this needs enough pull to keep the cups in place. To compensate, you'll (probably) need to go up a cup size.

2. Start On the Loosest Set of Hooks

This will ensure the longest life for the bra, and you can move inwards as the back strap stretches.

Style Notes: Nicole Ocran wears a strapless black bra with underwire from Fantasie.

3. To Check if a Size Works, Pop An Arm Behind Your Back, and Use Your Thumb to Pull the Strap Outwards

You should be able to pull it back only half an inch with resistance for a strapless bra.

4. Make Sure the Cups Aren't Gaping at the Top of the Breast

And depending on the style of the central section of the bra, the wires that meet in the middle should be sitting flat.

How to Make a Strapless Bra from Falling Down

Strapless bras shouldn't be falling down, so if they are, it will most likely be down to two factors: It needs to be replaced after owning it for a few years, or you never purchased the right size to begin with. Fit is integral, so try to test your strapless bras in person. And if you're still holding onto that bra that got you through high school, consider donating it to your nearest bra recycling service.

How to Make a Strapless Bra Stop Gaping

If your strapless bra is gaping, it typically means that your cup size isn't right. To avoid this, try going down a cup size and up a band size. Unfortunately, it really is a game of 'Goldilocks', testing out countless combinations till you find what fits best.

Should Strapless Bras Be Tighter?

As Rigby pointed out before, you may need to go down a band size and up a cup size to get the perfect fit. Strapless bras should never be tight, however. It's always the case that you should wear new bras on the loosest hook and eye, so if you feel that your bra is tight, perhaps think about letting it out first.
