There's a company over here called Long Tall Sally that do some nice clothes in sizes 8-20. My sister used to buy her trousers there - at 5'10" there wasn't really anywhere else she could go a few years ago, although since then some chains have spotted that there's a few tall people about and even (gasp!) people with big feet.

That reminds me, I have to shop for shoes again. :-( It's amazing how what looks cute in a size 5 looks like clown shoes in a size 8.

LTS do deliver worldwide, but then you'd be paying for delivery as well. Someone needs to get on and invent that teleportation machine.
