Today has been quite a groundbreaking day for Marks & Spencer as they opened their first London store in ten years at Colliers Wood. M&S devotee Erin O'Connor was there to cut the ribbon and looked stunning in a pair of black wide legged trousers and red top. She was joined by M&S Director of Clothing Kate Bostock.

O'Connor keeps a blog for Vogue and this week divulged that tonight she will be wearing a "Sexy black silk mini-dress with embroidery sporadically placed all over it" by Sofia Strazzanti. We can't wait to show you the pictures!
