L is for... Louboutin. The Double L is an iconic dress sandal showcasing Christian's flair for simple yet sophisticated design. Its upper consists of a delicate ankle strap with crossover detail at the back and front straps formed from two interlocking Ls. This season the sandal has been reworked with a strass-embellished front strap, while Specchio effect leather in stunning Elektra blue adorns the ankle strap, platform sole and 100 mm stiletto heel.
