Talons in need of some TLC? For one day only, 20 manicure stations are descending on Soho Square, with therapists offering £5 express manis using Models Own products. Pay more if you're feeling generous, because money raised via this nail-ien invasion goes to CoppaFeel! breast cancer awareness charity. As well as the manicures (you can book a slot in advance at www.birchbox.co.uk/manithon) there'll be refreshments from VitaCoco and Propercorn. For £12 you can also pick up an exclusive tee designed by fashion illustrator Sally Faye Cotterill for the event – get yours online now at www/birchbox.co.uk/shop.
