I’d never thought of shoes needing to be “plus size” but try to buy knee high boots at a department store and you’ll quickly find out it is! I LOVE knee high boots and I wear them constantly throughout the winter. I remember clearly the first time I tried on a pair that wouldn’t zip up around my calves. It was honestly heartbreaking.
Thankfully Torrid came to my rescue! I love their boots and I usually purchase at least one new pair each year.
Nordstrom also has some great options for wide calf boots but I haven’t personally purchased a pair from them yet.
Another one of my favorite winter staples is a vest! I love this one from Crown & Ivy, I own it in several different colors and wear a 2x!
