I am not the type of person to go overboard with pet clothes, but I have to be honest—this Fitwarm Knitted Tulle Sweater Dress is just too good to pass up. Dolly is officially the best-dressed girl in the neighborhood, and I am obsessed with the look. It is honestly the perfect balance of cozy and fancy. The top is a soft, warm knit that keeps her toasty on our winter walks, while the tulle skirt gives her that extra princess flair without weighing her down. It is surprisingly practical, too. It has a high-cut belly design that makes potty breaks simple, and the stretch in the knit fabric means she can still run, jump, and play without feeling restricted. Why it works: Finding winter clothes for small dogs that are actually comfortable can be such a chore, but this dress is wear-tested for easy movement. If you have a small dog or cat who gets cold easily, this is a must-have for your daily walks or even a cute photoshoot at the park.
