Saint Laurent's Billy ankle boots make a strong statement with vertiginous block heels and chunky plateau soles. Crafted in Italy from tactile caramel-brown suede, the pair fit closely against the ankle and come trimmed with logo-embossed burnished buckles. The teetering silhouette ushers up a distinctly retro feel, which we think is best complemented with either thigh-skimming skirts or playfully flared pants.
