Lee Cooper, the English denim brand, is celebrating its 100th birthday this year. They have many collaborations lined up with some of the world’s most respected designers, celebrities, sporting heroes and iconic brands, including Ora Ito. He’s a French designer who got well known for his Gucci Villa and his Hack-Mac designs.
Lee Cooper not only asked him to design this years logo, but also to do some clothing like this pair of denim and this t-shirt. He describes his style as ‘simplexity’, which you can tell from these designs.

These t-shirts were created as a memento for festivals throughout the summer i.e. Glastonbury. Washing detergent is screened onto the fabric, allowing the user to get their clothes as dirty as they want. Once the festival is over the detergent held within the t-shirt would clean itself and a full load of washing. After washed the t-shirt reveals a unique pattern and number.

That’s just one of the great ideas and designs by us.
