I remember seeing a group performing, of whom I am a fan. They were generally very well-dressed, but had got ready for the gig in a rush. The concertina player (who spent a lot of time, with one leg crossed over another) displayed a lot of bare leg and the WRONG coloured socks. And I found it distracting. (okay - lets not go into the reasons I found it distracting but I'll bet I wasn't the only one). Chaps - consider wearing longer socks - and of the right colour for the rest of your outfit.
