Tess Daly glam'd up last night as she attended an F1 party with her husband Vernon Kay. The couple looked very smart as they posed in co-ordinating ensembles. Tess wore a gorgeous black one shoulder frock which caught my eye. Her dress is by Olivia Rubin and is exclusive to My Wardrobe. The best news is that it's currently in the sale (£179, reduced from £257) and is perfect for any party. It has a sheer black layer with knotted shoulder detailing. Buying the dress will also mean you'll be giving money to Breakthrough Breast Cancer. What do you think of Tess's party ensemble?
