Mark Ronson was spotted yesterday leaving his hotel in New York, looking very much like Mark Ronson leaving a New York hotel: impeccably groomed, stylishly dressed and with the air of a man who's off to do something secret, cool and musical.

The DJ/producer was rocking his signature slick side parting (get the look here), a wicked varsity jacket and a cardigan: perfect layering for unpredictable spring weather. Then he added a simple block coloured T-shirt, some dark skinny jeans, and finished it all off with a killer pair of Nike Air Force 1s. Lovely stuff.
