Take it from a fashion editor - these incredibly chic shirts will become your everyday uniform

If you're trying to shop less, but spend more on quality pieces, then allow me to introduce you to the secret weapon in my own wardrobe: a well-cut shirt.

A year-round capsule wardrobe staple, whether you’re looking for linen, stripes, denim or plaid, With Nothing Underneath is the name that does it all. I already have four WNU styles, and when wondering what to wear on Christmas Day, it seemed clear to me that the brand's comfortable yet festive shirt in green and blue plaid had my name written all over it.

In the colder months, the shirts are an easy way to master the art of layering. Style a crisp white shirt beneath your best cashmere jumpers and add a blazer over the top for a timeless, elevated look.

When heading off on a summer holiday, my favourite lapis blue linen shirt makes both travelling and packing ridiculously simple. Wear it on the plane with linen trousers or leggings and your best white trainers, then team it with the matching co-ord boxer shorts on the beach when you touch down. Tie it over a simple black maxi dress for evening, and if you size up enough, you can wear it as a swimwear cover-up too.

It’s little wonder Meghan Markle is a fan of the label, which we’re adding to our list of the best British clothing brands.

Founded in 2017, WNU cites Carolyn Bessette, Jane Birkin and Charlotte Rampling as their style icons, but modern day wearers include Sam Taylor-Johnson, Claire Foy, Dolly Alderton, Suranne Jones, Josie Gibson and Ella Mills (AKA Deliciously Ella).

Founder Pip Durell is a former Vogue stylist and Tatler Editor, so it’s safe to say she knows her stuff. On the site she’s quoted as saying ‘it really just started with one shirt and went from there… I guess I thought that if I wanted this wardrobe staple then others might too.’

With prices ranging from £95 for a plain white poplin shirt to £230 for the bestselling silk styles, it might be a bit more than you’d normally spend, but it’s an investment that will definitely go far.

The quality is impressive, and they wash really well too. The blue and white striped poplin shirt is my office uniform, and the blue denim shirt has received lots of compliments at weekends.

The seriously impressive thing about WNU is that they’ve taken a really simple concept and absolutely perfected it. There are monogramming options to add a personal touch, and there’s even a clever ‘find your shirt quiz’ if you’re feeling overwhelmed by all the choice.

The shirts are available in UK sizes 6 to 18, and the sarongs, palazzo pants and caps are well worth checking out too.

What is a Boyfriend shirt?

Boyfriend shirts take notes from traditional menswear - as WNU calls it 'inspired by men’s tailoring and adjusted for women'. Button-down, boxy and oversized, they are loved by celebrities such as Victoria Beckham, Meghan Markle and Katie Holmes. The baggier the fit, the better, since the idea is to look like you've found it in your boyfriend's wardrobe. They work particularly well with blue denim and sharp tailoring.
