Just browsing their website and noticed that a few trousers, t-shirts, cardigans and their trench coats are available in tall sizes. There isn't much, but when you've got 36" legs, you appreciate whatever crumbs you're thrown! 
I've been crossing my fingers they'd bring their tall range over here for ages, so thought I'd share! (I'm on their mailing list and they haven't mentioned it. 
)
