This Uniqlo bra is so comfy it feels like a second skin - and it's under £20

I think we can all agree that this past summer was a hot one. The endless heatwaves made choosing an outfit each day a very tricky task, as I wanted everything to be as cool and easy to wear as possible, and that included my underwear. Even my best bras suddenly felt a little tight and uncomfortable as the temperatures soared, so I made it my mission to find some super breathable new pieces, and thankfully I found Uniqlo’s Wireless Relax Bra.

This well-designed bra is part of the Japanese brand’s AIRism range, which means it's made from a very clever fabric that promises to be moisture-wicking, odour-fighting, and cooling against the skin, as well as having plenty of stretch for comfort. The AIRism collection covers a lot of everyday basics, and I’ve worn some of the dresses before, but I'd never considered the underwear range until recently. Now that I’ve tried it, I can honestly see myself revisiting it again and again when I need to update my lingerie drawer.

The Wireless Relax Bra features all of the above cooling properties thanks to the technical fabric, but it also takes great care of my bust. It’s wire-free, which makes it wonderfully comfy, but still provides an impressive amount of hold and support thanks to the integrated cups and a built-in power mesh. It kept my boobs in check with zero rigid feel, and it's easily up there as one of the most comfortable bras I’ve ever worn.

I tried the bra in a lovely navy colour, which felt like a nice change from traditional black or nude styles, and there are currently four other colours to choose from, including grey and a peachy hue. The bra covers sizes XS-XXL, and it's only £19.90 – the affordability is another huge plus point for me, but the bra doesn’t feel cheap at all. In fact, this wireless style feels like a dream to wear, and I have worn it on repeat since discovering it last month.

Uniqlo Wireless Relax Bra: Comfort & Fit

If I had to use one word to describe the bra, it would be ‘comfortable’, as it pulls on easily and then sits neatly in position without feeling tight. I popped it on first thing and genuinely forgot I was wearing it. Sometimes a new bra can feel a little stiff, or it can take a while to get used to, but this one felt like a second skin on day one. I had no complaints right through to bedtime, and have enjoyed wearing it just as much regularly ever since.

While I wouldn’t necessarily wear the bra for a super busy day at work or running frantically for my morning train, I’ve found this one to be supportive enough for a normal day or a relaxed weekend, and it means I don’t need to decide between bra vs bralette, as it takes all the best bits of each to provide hold and shape while being stretchy and easy to move around in.

The wire-free design and subtly shaped cups contain internal power mesh, which works well to lift and hold my boobs, and the lack of any heavy padding means it sits invisibly under even the tightest of tops and has a lovely, smoothing effect. There are no clasps at the front or back, and the small adjusters on the shoulder straps look very sleek while being easy to slide up and down to find your perfect fit.

The AIRism fabric is noticeably cooler than some of my other bras, and it felt like a dream to wear on even the hottest of days. Summer might be over, but I will be sticking with this piece, as it will make a great and wearable base layer under my chunky knits and best winter coats over the coming months.

I’m a size 12 and a 36B, so I went for a size Medium, and it has been a total winner. The sizes go up to an XL, and while I imagine it'll be comfy for any shape and size, I'm not sure it would be fully supportive for anybody with very big boobs looking for an everyday staple - if you are browsing for the best bras for larger busts, this might not be the one for you.

Uniqlo Wireless Relax Bra: Style

I really like the minimal and fuss-free design, which comes without lace or bows, as it gives this one a modern aesthetic while still feeling very classic. It has a crop-top shape with a square neckline, which provides a little more coverage than some of my plunge or balconette bras, and works well under most separates, but it's worth mentioning that the higher-cut front does mean it’s not ideal for wearing underneath some skimpier or lower-cut tops.

The sleek material has a gentle sheen to it, and I really like the deep navy colour as it feels a little more interesting than my traditional lingerie, but without being too much. There are other colours to choose from too, and it’s currently available in grey, white, neutral, and a peachy hue.

Uniqlo Wireless Relax Bra: Care

A major plus point for this bra is that, despite being very technical, the Polyamide and Elastane fabric is easy to look after, and this piece can be thrown in the machine and washed at 40degrees on a gentle cycle. I have washed it a dozen times already, and it still feels like new. The built-in support means you don't need to worry about removing padded cups or anything beforehand, and after drying very quickly, it keeps its shape and stretch perfectly.

Uniqlo Wireless Relax Bra: Verdict

This bra really is light and breathable against the skin, and it was such a treat to wear during the hot weather, but now that autumn is approaching, I don't see myself packing it away anytime soon - in fact, I don't want to take it off! The super soft and stretchy material is really easy to move around in, and it sits neatly under clothing - all while providing a good level of support, shape and hold for my boobs.

This modern bra really has become one of my favourites. It looks good, feels great and keeps my bust in check, minus any rigid feel - I have zero complaints every time I wear it.
