The Custom-Made Cap The Stars Can't Get Enough Of...

When the likes of Sienna Miller, Cara Delevingne, Poppy Delevingne, Idris Elba and David Gandy get behind a fashion accessory, you know you're onto a winner. And that's exactly what's happened with Lucky Seven Caps.

We've spotted Sienna Miller, Cara Delevingne, Idris Elba, Poppy Delevingne, Madonna and David Gandy all wearing Lucky Seven Caps of late, and that prompted us to do some fashion investigation.

We found out that Lucky Seven Caps was set up by husband and wife team Mel and Jay Jay Burridge in 2004. What's unusual about the brand is that they only sell bespoke caps (no ready-to-wear items here, people) that feature embroidered patches inspired by fictional companies in films and TV shows, for example one of the first caps the pair ever designed used ENCOM motif from the movie Tron.

Make sense? Good.

The caps come in a variety of styles and colours - and you can pick a company badge that features in any film, from a mainstream blockbuster to an cult indie flick.

Wanna join Poppy, Cara and Sienna's stylish gang? Well Lucky Seven Caps are offering Marie Claire readers a 25 per cent discount on all caps. Simply enter the code MCXMAS when you come to pay. Offer runs until 20 December.

All the caps are custom-made to order and will be sent next day UK delivery until the 20 December. Shipping costs are additional but Lucky Seven Caps offer free shipping with two or more caps.

If you haven't already heard of this custom-made cap company, you need to get them on your radar immediately. Images of Idris Elba and David Gandy were taken by Rich Hardcastle
