Korean stylist, Shini Park tells PorterEdit why she is such a fan of a trench coat - It covers all manner of sins. Underneath you can be wearing something oversized, boxy or tight; pop a trench coat on top and belt it and you've immediately got your look. Max Mara's version is made from white wool in a streamlined cut and has timeless details, like a double-breasted front and buckled cuff tabs.
