It is a given that front row stars will wear Topshop to the Topshop show during London Fashion Week, but yesterday, Olivia Palermo wore a £22 ribbed, funnel-neck jumper to a show that wasn't Topshop. Olivia paired her brown lightweight knit with a black-and-white striped skirt to the Roland Mouret show, and then she changed into another outfit by the high-street giant for the Topshop show. She wore a yellow-and-blue gingham printed dress with an asymmetric hemline underneath a chunky camel jumper and paired with gold court shoes.
