Anthony Vaccarello spends hours trawling through SAINT LAURENT's vast archive for inspiration, often taking cues from past signatures. No doubt based on a style from the '70s, this coat is tailored from weighted grain de poudre wool in a sleek silhouette that can be cinched at the waist with the belt. The wispy feather-trimmed collar is detachable, so you can adapt it to suit different occasions.
