Remember a few years ago when people weren't sure what neckline they wanted on their jumper? We don't blame you if you don't, the crew neck won that fight so resoundingly you'd be forgiven for thinking it was the only option out there. As for us? Like most things in fashion, it goes in circles. So it'd be best if you buy all the good looking crewnecks you can now, before the world starts making V-necks again. (Mr Porter)
