‘to be worn effortlessly, without thought, or anything underneath’ – this was what our founder wrote in her notebook in 2017.

WNU is all about simplicity - paired back, laid back, timeless, effortless shirts - just like the woman who wears them. Our shirts are not about trends or fleeting style moments, but about a wardrobe essential in which to live a life.

We started WNU to create the perfect everyday shirt.

We're female-founded, independently operated since 2017.

WNU was inspired by men’s tailoring, and perfectly adjusted for women, the button-downs had to be sustainably sourced and stand the test of time.

With the collection now available in a range of organic materials from cotton workwear to travelling linens, WNU caters to the many different women we are throughout our week, from board meetings to weekend brunches.

We’re so happy you’re here. Welcome!


From the very start, we made a promise to ensure the shirts we give you are truly as good for our planet as they can be. WNU is still a small brand, but we are aiming to lead the way for a more sustainable fashion system.

A former Vogue stylist and Tatler editor, Pip combined her fashion knowledge and styling credentials with sustainability and her own very English, effortless approach to dressing.

‘Any brand, I believe, has a social responsibility to not only educate themselves but educate their customer on where their product come from, what their impact is and what they are made from'.

We need to be looking at the lifespan of an item of clothing, as well as the production and materials. As a conscious consumer you don’t want clothes that lose their fit after one wash, you want to invest in stylish wardrobe staples that are good to the planet and will last for years without a huge price tag.’

– Pip, Founder of With Nothing Underneath. .


With Nothing Underneath was founded with the aim to provide its customers with stylish basics from a company who cares, but not every woman's "basic" is a classic shirt. Many women and girls in the UK have their daily life hugely affected by period poverty, due to a lack of access to products. To help tackle this issue, WNU is proud to announce that they have partnered with The Hygiene Bank and are now an official Drop Off point based in South West London; our founder kindly invites anyone in the area to donate sanitary products, any donation, big or small, will be greatly accepted. These products will then be given to women and girls in the area who need them.

Please direct any questions regarding WNU's Drop Off point to phoebe@withnothingunderneath.com

Address: 47 Elizabeth Street, SW1W 9PP

Drop Off Hours: Thursdays and Fridays, 10am - 4pm
