My all time favourite jumpers are Uniqlo cashmere ones, but of course there isn't one in Edinburgh . Luckily I am going to London this weekend . I would be inclined to at least have a look in some of the discount cashmere shops Pruni- not a particularly tempting thought, I realise, but they might have something, and if you're going to Plaisir du Chocolat anyway you'll be in the right region....
