6. Waistcoats: Justin Timberake V. Adam Levine
ONLY these two men could STILL look good in a waistcoat and not get mistaken for their grandpa! Although Mr Levine has gone for an edgier slightly trendier take, we actualy prefer Justin's classic tweed one! Thumbs up gents, you both look great! Picture: Getty/PA
