Are check prints the new floral? Are brooches really back? Our fashion guru has all the answers in her March edit

• From Scandi brands to plastic-free fabrics: 10 women’s raincoats to style out drizzly days

We think before we buy these days, right? And so we damn well should. Shopping should not be a pastime. Style is eternal, not disposable. Each piece that has made the cut into my edit of March treasures has earned its place. A pair of £10 socks that are an instant wardrobe update. A £39 blazer that would pass for a designer investment. The ideal new-season nail polish for £8.

And you don’t have to buy anything at all for it to be worth having a look at my list. See below for my thoughts on what makes a boho blouse cool rather than twee, and a tipoff about the return of the brooch. That’s what I love about fashion: you don’t have to buy it to buy into it. But whatever you do, don’t buy anything until you read this.
