Long a standard-bearer of all-American style, Tommy Hilfiger always manages to effortlessly blend preppy and cool. This season he does it again, with a reinterpretation of the basic navy blazer so luxe it ought to come with a permission note: need not pair with khakis.

Created in collaboration with Italian wool mill Lanificio F.lli Cerruti, the limited-edition jackets are made from the finest threads, and sport a newly crafted crest on the buttons of the men’s blazer, with anchors adding nautical flair to the gold fixtures of the women’s.

Tailored elegantly at the waist, this version of the East Coast staple won’t box you in. Rather, it underscores shape and playfully mixes masculine and feminine, as if it were designed for Diane Keaton in “Annie Hall.”

What’s preppier and cooler than that?
