This would be in 2016, when a global pandemic was something that only happened in Hollywood movies. The Victoria’s Secret empire was already struggling, along with the idea of ​​women buying underwear for the male gaze, but this was still a prediction. Three years later, Kim Kardashian would launch the Skims clothing and lingerie brand, now worth $3.2bn (£2.6bn), so when Covid brought the world to a standstill a few months later and sales of traditional bras plummeted by 16 per cent (according to US market researcher NPD), both it and M&S were well placed to benefit from our rapidly changing lifestyles. So what’s it like to wear this hero bra? I tried the AE-cup version in a C-cup, as Halima had advised me to size down (there’s also an FH-cup style, as well as minimiser, post-op and nursing versions). For starters, the fabric is really soft: there’s no mistaking the feel of it when you’re blindly rummaging through your underwear drawer without your specs. Nor is there irritation from scratchy laces or tags. And the band doesn’t wrap – the perennial problem with sports bras. Plus, it looks stylish enough to wear as a crop top on its own. I wore mine on holiday in Italy last week with high waisted linen shorts and a matching shirt on top, worn open. I’m not alone: ​​M&S has sold almost half a million of these bras to date. I’m late to the party. M&S isn’t the only lingerie maker tapping into this demand for non-wired bras that cover larger cup sizes: Bravissimo has pretty lace bralettes that support up to a J-cup, from £36. John Lewis’ affordable Anyday range includes the Willow wireless bra, which goes up to an E-cup, £20. The most competitive seems to be the Zero-Feel bralette by Sloggi, £35 and the Spanx Bra-llelujah! non-wired bralette, £36. My only minor complaint is that while it’s supportive, the Flexifit doesn’t keep the breasts separate like a wired bra, which makes a difference to how your clothes hang. While there’s nothing stopping you from wearing it all day, every day, I’m most likely to wear it to a pilates class, walking the dog, or just around the house. When it comes to work or hanging out with friends, I still want that lift and separation to make my shirts and dresses look their best – and that, as far as I’m concerned, can only be provided by a traditional underwire bra. She proved me wrong about non-wired bras, though. They can be supportive and comfortable – even if you have a chest in the middle of the alphabet.
