Who we are

Once upon a shirt, Nicholas Charles Tyrwhitt Wheeler (whilst studying Geography at Bristol University - we might add) had the notion that he could make a better shirt at better value than anyone else in the world! He believed that all men; no matter their shape or size, where they may be in the world or their budget; should be able to own a Jermyn Street quality shirt. A proper shirt. A CT shirt.

That was over 3 decades ago and whilst Charles Tyrwhitt (it rhymes with spirit by the way) is still famous for proper shirts, these days we are about so much more than collars and cuffs. Our purpose is to "make it easy for men to dress well". We take care of a chap's entire wardrobe, providing stylish solutions for every occasion. We make sure he gets what he wants, when and how he wants it.

With a unique product offering delivered with exceptional customer service, Charles Tyrwhitt is a world-known, well-loved London-based brand with stores throughout the United Kingdom, France, and the United States. Our Global Head Office is in London Bridge, where our teams that support our online presence in North America, Canada, Europe and Australia are based. We have a small Manhattan office for our US Partnerships and US Retail support teams, and our Distribution Centre and Contact Centre are based in Milton Keynes.

At Charles Tyrwhitt we believe in doing the right thing. That means making our products properly and sustainably, making our business work for our people, our customers, and our suppliers and giving back to charity to support those in need. We're taking a good hard look at our social and environmental impact, and always looking for ways to be better.

'I am Proud and Free to be me!'

When it comes to our people, we really do "Give a shirt".

Tyrwhitteers (our people) are a diverse, passionate and entrepreneurial bunch. We enjoy a fun, engaging and rewarding culture, where everyone is empowered by our 3 BE-liefs which are; "BE the BOSS", "BE the CUSTOMER" and "BE the BEST".
