If you're in need of a treat to pep up your Monday then look no further than the brand new T-shirt collection designed by Lulu Guinness for Uniqlo.

This is the designer's second collection for the high street brand's UT range and it channels the same fun, playful vibe that has made her eponymous accessories line such a favourite with everyone from Jessie J to Alexa Chung. Polka dots, long-lashed eyes, a mouse and Lulu’s signature red lips are all printed across the mostly monochrome pieces.

The T-shirts, all £12.90, are available at www.uniqlo.com right now.
