Sian Welby's elegant M&S top and trousers prove block colours are here to stay
Her top-to-toe blue outfit makes styling this trending tone so easy
There’s nothing like sunshine to get us into bright and colourful outfits and, as we reach the end of summer, there’s no time like the present to make the most of it.
Colour blocking and drenching make light work of wearing bold hues, with the technique of using just one colour from head to toe meaning you don’t have to worry too much about experimenting with complementary hues. Proving the result is so eye-catching, Sian Welby styled up an all-blue outfit from M&S, pairing the sleeveless knot detail top and a complementary pair of tailored wide-leg trousers by Autograph.
It’s not just the striking blue tones that make this look a standout, though they are spot on the fashion colour trends for 2026 and have been dominating summer styles this year. Sian’s outfit is made all the more stunning by the clean-cut tailoring of her knot-detail top, and the elevated fit of her tailored trousers makes this look one worth bookmarking for any dressed-up occasion this season.

The loose-fitting, wide-leg cut of these M&S trousers is balanced out by a flattering high waist and front pleat detail that adds structure and sophistication. This balance makes them perfect for dressing up and down, so they're super versatile.
With reviews calling this top 'so smart' and 'super comfortable,' it's no surprise that it's quickly selling out online. The sleeveless style still feels incredibly wearable, as it completely covers the shoulders and the high neckline adds modesty. But it's really the stunning pale blue that makes this bargain buy a standout.
Blending style with comfort, these trousers sit at a natural waist height, and the wide leg is balanced by a slightly more fitted shape at the hip and thigh. These are 100% linen, which is great for late summer and early autumn weather.
This top is proof that not all T-shirts are made equal. For starters, it's made from a breathable modal blend that adds a luxe touch and feel. But the real stars are the drapey fit and structured cap sleeves that add elegance.
The summer-ready, cornflower blue hue of these trousers is so eye-catching. The shape is just as stunning too, with the style sitting high on the waist, while pressed front pleats add sophistication.
While this H&M top doesn't have the same knot detail as Sian's, it is cut to an incredibly similar shape with its fitted look, high neckline and draped short sleeves. Pleated details on the side create a beautiful drape effect that's simply stunning.
Colour blocking might seem like a daunting trend to try, but it’s actually incredibly easy to pull off. Whichever colour you choose to base an outfit around, try opting for a darker take on the shade with your trousers and lift the look with a softer or pastel hue on top.
When it comes to accessories, you can play around to give colour-blocked outfits like Sian’s added versatility. Try a matching bag and shoes for a one-shade statement, or introduce a party-ready flair with some metallic heels and a clutch. And don’t forget you can always soften things by slipping into your trusty white trainers and keeping your jewellery to a minimum.
With all these styling opportunities, you’ll likely find that this fresh, timeless and elevated look is a lot more versatile than you might think. Whether you’re heading out for a garden party or fancy occasion, looking for smart casual outfit ideas that can double up as date night outfits too, or want to up the office wear ante, you really can’t go wrong with some sophisticated colour blocking.
