Ever since I saw the pictures of Jeanne Damas at the Dior show in a belted sleeved denim jumpsuit, I have been on the hunt for one for myself. Denim all-in-ones might seem like a bold statement, but the retro piece actually works for all of the events in your calendar and can be really flattering if you find the correct fit. On holiday you can wear it with a raffia tote and sandals as a beach cover-up, or you can pair with your cosiest coats and sturdiest boots to battle this week's Beast from the East.
