I'm probably not going to convince many people but when wearing jeans and trainers the best look to go for is Freddie Mercury. Seriously, it's deliciously retro without being musty, all you have to do is take some white '80s trainers or plimsolls, team with faded tight blue jeans and a white vest. If you want to give the outfit a bit of Freddie glam add a volume knob brooch in his trademark colour, a Queen bomber jacket and a canvas bag with his face on it. All you need know is a shaggy rock haircut and you're all set.
