Dries Van Noten's navy suit is as classic as they come – we can all but guarantee it won't go out of style. It's tailored for a comfortable fit from a smooth, fluid cotton-blend that's infused with wool for added heft. The jacket is cut with classic notch lapels, a flexible single vent and two-button close, while the trousers have unfinished hems, so you can have them altered to your preferred length.
