Moss regularly tops off her outfits with a trilby. She recently sported a cream fedora to the wedding of Primal Scream singer Bobby Gillespie.

But her boyfriend Pete Doherty, another trilby fan, failed to win the male crown.

Instead the accolade went to pop star Robbie Williams.

Philip Wright of milliners Walter Wright said: "A hat is the final statement in personal style and to be recognised as one of the nation's most stylish hat wearers is an accolade for individuality and distinction."

Last year's winners were royal Zara Phillips and Sir Elton John.

Moss and Williams were chosen by consortium Luton First, to promote the town's reputation as the centre of hat-making.

A spokesman said: "Kate manages to wear the most elaborate and extravagant millinery designs with great confidence and aplomb and, most importantly, without the hat seemingly wearing her.

"She has the face to launch a thousand hat collections and has done much to promote hat wearing in recent years."

As for Williams: "He doesn't take fashion too seriously and appears to treat clothes as a bit of fun."
