Macs are no longer just the jacket of choice for grannies, they're becoming a wardrobe essential...

If there's just one thing you invest in this autumn, it has got to be a mac (also know as a trench coat).  Burberry have made them cool again and all the celebs wear them when they want to look glam but still stay warm.  The Gossip Girls seem to have one in every colour...

We love that Breakfast At Tiffany's inspired scene in Gossip Girl where Blair tries to find her cat in the pouring rain, just like fashion legend Audrey Hepburn. Blair is the undisputed queen of chic, so we can't wait to recreate her polished look.

Oh but look, Blake is also working the trench trend!

Blake wore an elegant mac to arrive at The Late Show, before shedding it to reveal her glam evening dress.
