30 Under-£100 Autumn Buys I Can't Stop Thinking About

Ask any of the Who What Wear editors, and they’ll tell you there's nothing we love more than finding joy-inducing yet affordable pieces that stand the test of time. We firmly believe that no matter the price point, everything in our wardrobe should be viewed as an investment and that, luckily, the high street is fully stocked with such gems. In fact, some of our most-loved and most-worn sartorial heroes are also some of the most affordable pieces in our wardrobes. 

But where do you start when hunting down these budget-friendly and stylish hits? That's where I come in. Now that the autumn collections are starting to filter in, I deep-dived into the new-in pages of some of my favourite high-street brands to craft the ultimate list of expensive-looking new-season hits, all under £100. From beautiful knitwear to hero accessories and sleek tailoring to party-season pieces worth snapping up now, there's something for every style and every budget here. 

Scroll down to discover the under-£100 pieces I’ve got my eye on right now.


Half-zip and striped? A winning combo.
