3 Classic Shoes Ashley and Mary-Kate Olsen Wear Nonstop

We aren't prone to playing favorites, but it's safe to say that Ashley and Mary-Kate Olsen are two style icons we will always turn to for outfit inspiration. Blame it on our enduring nostalgia for '90s fashion muses, but whenever the Olsen twins step in front of a camera (which, we should add, isn't very often), we're poised and ready to take style notes.

Given that the pair rarely deviate from their signature all-black aesthetic, it should come as no surprise that their footwear choices skew as "boring" as well. Ahead, we're breaking down the three classic shoe styles we've spotted Ashley and Mary-Kate Olsen wearing nonstop over the years. From on-trend kitten heels to practical and polished loafers to ankle boots, these are the timeless wardrobe staples that the stylish sisters wear on repeat.

Scroll on to see how Mary-Kate and Ashley Olsen style three "boring" shoe styles and shop similar pairs for your own closet while you're at it.

Kitten Heels

Although kitten heels are a major summer shoe trend, they're also a classic style that will endure the test of time, as Mary-Kate and Ashley are obviously very well aware.

Here, Mary-Kate deviates from her signature all-black aesthetic with a pair of bright red kitten heel pumps.

Meanwhile, Ashley pairs croc leather mules in a modest kitten heel silhouette with a monochrome black ensemble.

Loafers

Ashley and Mary-Kate also have a penchant for practical and polished loafers, stepping out in the style for occasions from red carpet appearances to airport arrivals.

Donning the classic shoes while walking the red carpet, Mary-Kate demonstrates the power of patent leather loafers.

Here, Ashley makes a case for bringing back oft-overlooked tassel loafers—and showing them off with a pair of cropped pants.

And now, leave it to Ashley Olsen to inspire us to step up our airport outfit style by wearing loafers with black skinny jeans.

Ankle Boots

A favorite of Mary-Kate in particular, ankle boots are a classic shoe style the fashion icon frequently wears with her signature all-black ensembles.

True to form, Mary-Kate polishes off an all-black outfit with a pair of timeless black leather ankle boots.

Here, however, Mary-Kate adds a pop of color to an otherwise all-black look with a pair of on-trend square-toe snakeskin boots.
