Polished, feminine, elegant. The Bunny Knot poplin shirt is crafted in cotton poplin with a brass knot button and cufflinks. The simple yet distinctive knot is a mark of craftsmanship, inspired by a chair cushion Tory discovered in the Antigua home of legendary horticulturist and philanthropist Bunny Mellon. An abstract interpretation of our iconic Double T. The poplin shirt is a signature foundation piece to wear year-round.
