Supermodel Kate Moss arrives at LAX yesterday

She may have the world's best dressed woman title under her belt, but it seems even Kate Moss suffers the odd unfashionable wardrobe malfunction.

The supermodel was snapped arriving at Los Angeles Airport from Miami yesterday, dressed in a white top and dark jacket, and figure hugging jeans - with the fly open.

It seems as if in all the excitement of being back in LA, Miss Moss had forgotten to zip her fly up.

But even her recent wardrobe hiccup can't take the shine off her Best Dressed woman accolade.

Moss often rates well in best dressed ratings having topped another celebrity best-dressed list, this time in Glamour magazine.

She came in at number four in 2007, but this year beat previous winner Kylie into 19th place.

Glamour consulted industry experts to find the world's fashion queen.

Moss won out not only over Kylie but also beat Jude Las's fiancee Miller, whose dress sense has heavily inspired this winter season's clothing trends.

The supermodel is currently enjoying a holiday in the U.S. where she has busy playing mother to five-year-old daughter Lila Grace.

The model landed in the U.S. last week with Lila Grace and a group of friends including Jade Davidson, the sister of Sadie Frost, and her hairdresser James Brown.

Kate has been in full-on mummy mode, taking daughter Lila to Disneyland at the weekend and then to Universal Studios Hollywood.
