16 Seamless Bras That Are So Comfy You'll Forget You're Wearing Them

Pretty much all of H&M's seamless bras have five-star reviews. Its size range isn't as inclusive as we would like, but if you sit anywhere between an A and D cup, you can enjoy the subtle padding and a breathable finish this bra offers.

Another affordable option, this Uniqlo bralette probably qualifies as the most invisible of all our picks. The brand's Airism technology makes this option feel as light as air. Plus, it's quick-drying and sweat-wicking, so you can keep your cool all day long.

Even those without a shred of interest in shapewear and underwear (beyond the essentials, that is) have heard of Skims. Kim Kardashian's brand is worth the hype, and not only because of its size and skin-tone inclusivity. This wear-under-everything bra spans sizes SSX to 5XL.

This stylish and supportive bra caters to a refreshingly broad spectrum of bust sizes, featuring peekaboo mesh detailing and a tasteful selection of colourways. No underwire needed here—customer reviews point this out as a particular highlight, especially since they feel just as lifted without it. 

This cheerful lilac number claims to have the minimum number of seams possible in a bra, resulting in a simple yet pretty design. It has removable cups and adjustable shoulder straps, so you can tailor this lingerie piece to how you like it.

This is branded a sports bra, but once you try it on, you'll want to wear it all day. Girlfriend Collective's activewear separates have garnered quite the fan base, not least because of their impressive sustainability credentials. Would you believe this bra is made from recycled plastic bottles?

At that price (just £5 per bra!), you'd expect a lot of negative reviews, but customers have been super impressed by how soft these are and how discreet they look under clothing. Sounds like a great everyday option to me.

This square-neck bralette has a classic cut, but important details including the thick straps, wide band and crucial lack of seams make it a standout. Crafted from regenerated nylon, it's good for the planet, too. Customers with smaller chests particularly love this one.

You'll find exclusively positive reviews of this bra on Hanro's website, with people praising its gentle support and confidence-boosting effect. My main takeaway: If you're a C cup or smaller and want to feel unrestricted, you should give this a go.

Achieve a significant push-up look without relying on underwiring and bulky padding. This staple buy has over 800 rave reviews—something tells me it's worth trying out.

This style has memory foam sewn into the cups, and if that doesn't scream comfort, I don't know what does. Multiple reviewers claiming this is the best bra they ever bought convinced me to add it to my basket.

If you prefer to sleep with some support, this loungewear bra is just what you've been looking for. Of course, you can also wear it in the daytime—you might have to, since its ribbed finish is so gentle on the skin you won't want to take it off.

Another Skims piece, since I couldn't pick just one. This bra comes with a scoop neck that's incredibly flattering on all body types (as the name suggests). It's moisture-wicking, so you don't have to worry about getting sweaty when you're on the go all day.

If you have a larger bust, you might find the idea of going braless a little daunting and unappealing because you likely need the support. This Freedom bra offers the best of both worlds for up to size HH. If you want to see how it looks on other women, there's a section with customer images on the website. So helpful.

The only problem with this bra is trying to decide on a colour. Available in three different ranges that cover all shapes and sizes, this game-changing piece of lingerie is simultaneously sexy and secure. Okay, it does technically have seams, but they've been flat-stitched for a seamless look and feel.

It's a fashion indsider's fact that Weekday make great bras (and briefs, by the way), so the popularity of this seamless option is no surprise. It's thick enough that you could even wear it as a micro-crop top styled under a blazer or oversized shirt.
