Whether it's a statement design feature or subtle detailing, a zip dress can transform an otherwise simple dress into something that can exude anything from subversive punk style to a sexy suggestiveness and playful appeal. A chunky exposed zip can add an edge to any piece, whether it's workwear or a basic shift, while a more subtle addition can be a practical design feature that allows you to show off exactly what you want to. Team a zip with a sleek bodycon style and vamp up the glamour, or keep it understated with a casual zip back dress.
