I’ve been washing my white linen trousers on repeat and rotating the same handful of office-appropriate dresses in a bid to stay cool.With the warm weather showing little sign of easing up, I decided it was time to refresh my summer wardrobe - but I didn’t want to spend a fortune. Surprisingly, the answer lay in an unlikely place: the supermarket.Yes, every look I’m wearing here has come from the clothing aisles of Asda, Sainsbury’s, Tesco and Morrisons. Today, there’s no stigma attached to shopping there. Any fashion-conscious woman will tell you that supermarket fashion is a revelation, offering designer-looking pieces at a fraction of the price.So I’ve combed through the latest collections to find the standout pieces that are heatwave-ready, for you to pick up on your weekly shop.Starting with dresses, Tesco’s F&F Edit range has produced a winner in the form of a strappy chocolate-brown maxi (22.50). The sheer mesh overlay skims the body, making it the perfect choice for balmy evenings. Dress, £22.50, tesco.com; sandals, £12.50, asda.com/georgeMorrisons wouldn’t usually be my first stop for occasionwear, but this spot-print maxi genuinely surprised me. The adjustable straps and floaty tiered silhouette make it ideal for warm weather, while the oversized polka dot print has a distinctly high-fashion feel. At just £22, it’s a sophisticated choice for summer parties. Polka dot dress, £22, available in select Morrisons stores; sandals, £12.50, and sunglasses, £6, asda.com/georgeIf you prefer separates, this peach co-ord from F&F (£45.50) is another standout. The soft hue looks particularly flattering against sun-kissed skin, while the elegant flared silhouette elevates it from supermarket to super-chic. Halterneck top, £18, and matching skirt, £27.50, tesco.com; sandals, £12.50, asda.com/georgeCo-ords are also one of the easiest ways to look polished with minimal effort. This geometric set from F&F could easily be mistaken for a Reiss set I’ve been eyeing up, but rather than the £290 price tag, it comes in at just £40.50. Smart enough for the office while relaxed enough for drinks in a pub garden, it’s one of my favourite finds. Halterneck top, £18, and matching trousers, £22.50, tesco.com; sandals, £12.50, george.comJeans are the first thing I abandon when temperatures rise, opting instead for loose-fitting trousers like this lightweight barrel-leg pair from George (£35). There’s no thigh rub or risk of a Marilyn Monroe moment in a sudden breeze and, teamed with the brand’s cropped crochet top, it makes for an effortless festival-ready look. Crochet top, £20, and barrel leg trousers, £35, asda.com/george; sandals, £20, sainsburys.co.ukI’m usually a bikini girl, but recently I’ve found myself gravitating towards swimsuits. I love Hunza G’s signature crinkle styles but, with prices starting at £170, they’re a significant investment for a garment you only wear a handful of times a year. Thankfully, George at Asda has created a remarkably similar version for just £18, complete with a flattering low scoop back. Pair it with Tu’s ultra-wide striped trousers (£20) and George’s rust-coloured straw tote (£14) and you have an easy beach-to-bar outfit. Swimsuit, £18, and bag, £14, asda.com/george; trousers, £20, and jelly flip flops, £7, sainsburys.co.uk A good vest top is another summer essential, and this bright red version from Tu (£16) is embellished with fun sun-shaped buttons. For extra style points, embrace colour-clashing and pair it with the green checked hanky-hem skirt, currently reduced to £12 in the sale. Button detail vest, £16, and check midi skirt, now £12, sainsburys.co.uk; ballet flats, £6, asda.com/georgeAnd finally, footwear. Sainsbury’s gets my vote for the strongest selection this season. My standout pair has to be the jewel-detail sandals (£20). I’ve been wearing mine non-stop and can confidently say they’re among the comfiest shoes I own, while still looking stylish. And on my next visit? I plan to snap up a pair of bright red jelly sandals (£7), which add a playful pop of colour to any summer outfit.
