We see lots of plaid button-downs and accessories, but Nicky Hilton's plaid puffer coat is a trend we'd love to hop on! Her specific coat is from Ellie Mae Studios, a Canadian label and also a celebrity favorite. This budget-friendly one we found from Express is on sale, too. You can throw it over your neutrals like she does with basic jeans and a sweater, plus cute loafers. Her Birkin bag is something to envy, as they always are, and this rich tan color is a personal favorite!
