Of those of us who are frequent shoppers on the M&S website, many of us will be all too familiar with the Flexifit™ Wired Full-Cup T-Shirt Bra. Since its launch with the retailer a few years back, it's amassed over 3,000 reviews, which easily makes it one of the most reviewed bestsellers at the brand. In fact, shoppers have taken to the review section to dub it the 'most comfy' bra that they own.
Made from a soft blend of comfortable and stretchy fabric, the bra uses Flexifit™ technology to ensure that it moves with you for all-day comfort. With full-coverage cups and a seamless t-shirt design, the bra practically disappears under clothing. No more seams or show-through ruining your outfits! The ultimate everyday bra.

Available in cup sizes A to E across band sizes 30 to 42, the M&S Flexifit™ Wired Full-Cup T-Shirt Bra has long been a bestseller on the website. It currently comes in dark magenta, black, white, rich quartz, rose quartz, opaline, rich amber and topaz.
As well as the bra's seamless fit that makes it look much more expensive than it is - (think SKIMS on a budget) - we love that it comes in a range of inclusive nude skin tones, too, where some high-street brands can fall short. Available in five colourways that resemble nude tones, it also comes in black, white and magenta. In our opinion, it's a must-have in your wardrobe, and shoppers can't help but agree.
One delighted customer took to the review section to say, 'Probably my most comfy bra, I have lots of colours of this. It is pretty basic but great for everyday under most things, smooth fitting under tighter tops.' While another commented, 'This is my favourite bra that I have in several colours. It washes well and lasts for ages. Such a good price for an everyday t-shirt bra. Would recommend.'
Many reviewers went on to praise the bra's comfortable and supportive design, particularly commenting on the soft cups that mould to your bust, giving you a flattering shape with just a light amount of padding. A shopper even claimed that they 'forgot they were wearing it'. Sounds like a hug in a bra, if we're honest.

It only helps that it's so cheap, too. With bras being so expensive these days, many will find that it can be a real struggle to spend anything less than £45 for a good quality bra. Especially those with a bigger bust! However, M&S's option, which comes in at under £20, shows that you can still get an accurately fitting, supportive bra of incredible quality - even when you're shopping on a budget.
It's clear to see that years on from its launch, the M&S Flexifit™ Wired Full-Cup T-Shirt Bra remains a reliable favourite with shoppers at the retailer. That's the indicator of a pretty impressive bra, right there. If your underwear drawer is looking tired and in need of a refresh, why not see what the fuss is about and stock up on this 'exceptionally comfortable and supportive' M&S bra? Especially while it's so cheap... did we happen to mention it's only £16?
