I share outfit ideas on TikTok and Pinterest all season, and the piece that does the most work in winter is a good knit: it turns jeans and a tee into an outfit and keeps you warm from school drop-off to Sunday dinner. These are the cardigans and sweaters I've saved with that French countryside feel: ecru and embroidered Sezane cardigans, soft alpaca, a classic cable knit, a cozy fringe shawl, a striped rollneck and an easy camel half-zip. Some are investment pieces worth saving for, and plenty are easy on the budget. What's the one sweater you wear every week from November to March?
