Thanks, fleurbird - not sure of the answer yet but off to work just now so will think again later. The clue previously given for 9 was You wear it well and 15 seems to be foxing everyone! Good luck!
Back again, fleurbird! The penny finally dropped with your clue about the TV programme being a favourite with quizzers! I'm assuming your comment about my clue means it would make more sense to tell you that the four pictures are all makes of clothing! Thanks for your help!
