Just like a bodysuit or slip skirt, most wardrobes benefit from these simple, versatile underpinning that works in harmony with so many other pieces you own. I exclaimed when the press release for Spanx founder Sarah Blakely's latest venture landed in my inbox.

I'm always struggling to find slimline crop-tops that work well under pieces I want to keep wearing in the colder months, such as this sleeveless jumpsuit. They're not remotely itchy, and despite looking alarmingly small when you take them out of the packet, they do stretch a lot. An editor from the magazine tested them out at fashion week and said they made her arms look "slender and toned. So whilst each top does feel like a little hug (andthey add atouch of firmness to the overall look of your arms), I wouldn't say they're working incredible miracles.As well as a few basic colours, you'll also find versions in more elaborate knits like lace (and leopard print! Given that Blakely is the woman that has revolutionised the underwear market and given women around the world the sculpted waists and bums needed to carry them through a decade of bodycon dress styles, I thought I’d better trust her. Additionally, if you’ve embraced the modest fashion movement, Spanx's Arm Tights just might be the things you’ve been looking for.

There would be no point in having a sucky-in, long-sleeved layer underneath that, unless the outer top’s silhouette was also skin tight.

Unlike traditional layering shirts, this garment has no seam up the arms for 360 flawless arm coverage! With the white, pastel and light-grey shades, you'll want to consider your bra options carefully if wearing Arm Tights without another layer over the top. Once I worked out which way around the arm tights were supposed to go (I originally put them on back to front), they were actually quite comfortable. The only aspect I remain unconvinced about is that you can't escape feeling like you’ve got tights on your arms. There's also no denying that they do make your arms noticeably more streamlined, in the same way that Spanx's high-waisted pants do.

Whether you're planning on covering up or want their "slimming" capabilities, keep scrolling to see what happened when I put them to the test. And within this new Spanx creation lies a potentially useful little layering tool that could be a great part of your lingerie capsule wardrobe.Spanx, the billion-pound underwear brand, has launched its new product in the UK this week; Arm Tights.

I, and everyone I know who has ever declared their bingo wings to be a ‘body hangup’, all have one thing in common. founder Sara Blakely is keen to apply her magical tightening, lifting, and smoothing fabrics to another of our problem areas, our bingo wings. The arm tights take the form of a crop top (designed to be less bulky under your clothes), in basic block colours and are therefore easy to layer underneath shift dresses and sleeveless tops, instead of a long sleeve T-shirt or polo neck, for autumn.Right now, it's passé to have a Trinny and Susannah–style discussion of "bingo wings" or to even consider the concept that women might want to cover up their arms for fear of the aforementioned wobble.
