Meghan Markle *loves* this ultra-stylish slipper brand

There's no denying that the "Meghan Markle effect" is real. In fact, just about anything she touches immediately sells out (remember her J.Crew coat?). One of Meghan's best-kept fashion secrets? Birdies, an adorable brand reinventing house slippers.

The former "Suits" actress has been a longtime fan of the brand's best-selling 'Blackbird' shoe -- a simple black loafer with ultra-lux cushioning that makes you feel like you're walking on a cloud. In fact, Meghan has posted photos of herself wearing the shoe on her now-defunct Instagram account.

While Meghan's favorite loafer is out of stock, you can still grab a similar pair along with a ton of other eye-catching styles we love from the brand's new 'Fall in Love' collection. Our favorite? The 'Starling' slipper in a black crystalized style that practically screams holiday party.

Check out the list below for our favorite Birdies picks!
