Sonia Rykiel is a designer I've always liked, but I only recently bought my first piece - this slouchy, casual Sonia by Sonia Rykiel rainbow knitted cotton jumper dress in the My-Wardrobe sale. Here I'm wearing it amongst the poinsettas at the Marché des Fleurs in Paris with red suede ALDO heels and matching lipstick, because flower markets and brightly coloured stripes cheer up even the coldest winter days.
