Kate Middleton is no stranger to skinny jeans outfits. In fact, they seem to be her casual attire of choice—likely because they look polished and classic, which describes her aesthetic in a

nutshell. She's particularly fond of black skinny jeans, and those are what she wore today in Scotland during the United Nations Climate Change Conference.

In addition to her black skinny jeans, Middleton wore a black turtleneck, combat boots, and one of 2021's most casual winter trends: a quilted vest. Hers is an oversize green vest from Ganni, a brand that has excelled at making quilted nylon outerwear cool. 

Quilted nylon vests may be trendy this season, but they're also quite functional. They're perfect for the "cold but not too cold" days we're currently getting, and they'll serve as a great layering piece on colder days when you also need a coat.
