The UK’s GQ magazine has launched a new iPhone app in partnership with designer e-commerce site Mr Porter, the men’s arm of Natalie Massanet’s Net-a-Porter.

The GQ Style Guide labels itself the essential men’s fashion manual, offering advice on “what to wear, how to wear it, and where to buy it”.

Daily updates cover everything from the best suits, shirts and shoes, to the latest trends from the catwalk shows.

There’s also an “Ask the Style Shrink” section, dedicated to answering fashion questions, and a “How to Dress” reference for specific events.
