Why you should wear them

Dressier than flat sandals but not as formal as a heeled pump, the mule is the cool girl's way of acing the smart-casual dress code.

Cult bag label Mansur Gavriel debuted its shoe line for spring with a colourful and minimalist range of suede mules in shades such as bubblegum pink and yellow, while other luxury fashion labels such as Celine, Gucci and Proenza Schouler had more elaborate designs with embroidery and embellishments.

For everyday style inspiration, look to Australian photographer Zanita Whittington and Brit model Alexa Chung, who have paired their mules with patterned jumpsuits and A-line skirts.

How to wear them

• As the style exposes much of the ankle, that means there is less support around the area.

For more grip when you walk, choose mules with wide straps that cover most of your feet.

• Match the style of the mules to your outfit.

Mules with dainty and slim stiletto heels go best with feminine dresses or sleek trousers, while mules with block heels balance out edgier and baggier outfits such as jumpsuits and boyfriend jeans.

• Avoid wearing mini skirts or shorts with mules.

Mules help to visually elongate the leg from the front and back, thanks to the lack of ankle straps, but too much exposed skin can look tacky.

When in doubt, stick to cropped trousers or midi skirts.
