I know there's a lot of Mad Men fans out there, so The Fashion File: Advice, Tips and Inspiration from the Costume Designer of Mad Men by Janie Bryant will almost certainly find a ready-made audience.
Janie Bryant created all of the looks seen on cult show Mad Men, with this book offering a peak inside the dressing room, revealing how the looks of various characters are developed, as well as tips on where to find quality vintage clothing and accessories, plus ideas on pairing authentic pieces with modern clothing and accessories. Not just for women (although that's the backbone of it), there's also a section on giving men a touch of the Don Draper. Probably more Mad Men-inspired than focusing purely on the TV show, but if the show if your latest obsession, probably worth checking out.
It's got a shelf date of 14th October 2010, with Amazon doing pre-orders for the 192-page hardback book right now – the price is £14.44.
