John Mayer - April
There is a fine line between laidback and looking like a hobo, as John Mayer proves here. Winning brownie points for his jeans, Mayer ruins it all by wearing his shirt undone underneath what looks like a picnic blanket. Printed shirts are big news for summer – wear one buttoned up to the neck or totally undone over a basic T-shirt. Opt for a blazer or relaxed trench to weatherproof your outfit.
