I Gasped—H&M, COS and Mango Just Dropped the Most Expensive-Looking Spring Buys
H&M, COS and Mango's spring 2026 collections are full of elegant buys, and I've handpicked the 19 pieces that will sell out first.
There's no denying that the great British high street has come a long way in recent years. With every new season, our favourite affordable brands seem to outdo themselves, from honing in on the latest trends to creating pieces that could easily pass for triple their price. With the rest of the spring season and summer days stretching before us, my wardrobe is ready for a fresh infusion of expensive-looking warm-weather buys, and right now my favourite pieces all come from the spring collections of H&M, COS and Mango.
Whether renewing your workwear collection or planning out reliable, sleek outfits for your weekend plans, the high street always comes through with elegant options. The only downside is that searching for these pieces can take considerable time and an eye for the purchases that will earn their keep in your wardrobe year after year. Thankfully, I spend all day exploring the new-in buys to save you time and bring the most worthwhile high street purchases together in one curated edit.
The arrival of bright days has thrown my wardrobe straight into a new gear. Linen trousers are back as a wardrobe essential, and COS has just restocked its best-selling pair, now with a bold barrel-leg cut. Dresses are back in our everyday rotations, and whether you're looking for a languid throw-on style or a more fitted everyday piece, I've found a selection of elegant styles that feel incredibly current but will also outlast the moving trends. Finer details note the seasonal shift as linen fabrics, raffia materials, and suede textures return as calling cards of the warmer months, and you'll find these spring signals applied to a series of sleek pieces from shirting to accessories. As the best high street pieces tend to move quickly, let's get straight to it. Keep scrolling to shop the most expensive-looking warm-weather buys from H&M, COS and Mango right now.
