Kate Middleton’s wardrobe is full of must-have staples that can work in any woman’s wardrobe. For example, the humble blazer. Kate is clearly a fan, often seen sporting a smart blazer over a tee and jeans or trousers. In fact, it’s somewhat become her go-to look for those in-between occasions that don’t require a ballgown but where her beloved trainers and chic tracksuits or jersey jumpsuits won’t quite cut it.
