Ugg season is officially upon us. In fact, as I type this story, I'm sitting in my desk chair wearing my go-to Ugg Scuffette II Slippers ($95). While I'm wearing run-of-the-mill shoes like a plebeian, Blake Lively's pair is significantly harder to get your hands on. Photographed in New York City with husband Ryan Reynolds, Lively wore the Ugg x Opening Ceremony Tasman Slippers that are currently marked up significantly on Poshmark due to their lack of availability.

With a cool buckle detail and a trendy platform sole, it's no wonder these mules sold out lightning fast.

As for the rest of her cozy outfit, Lively went for a tonal look with shades of blue. She layered a lighter-hued sweatshirt under a dark navy-blue coat, finishing off the look with a blue Chanel bag. Scroll down to see how Blake Lively styled the covetable Ugg boots and shop other pairs for yourself.
