Thanks everyone!
The Lacy one it is.
Have been soooooooo naughty, just popped into town and bought some knee high boots I have been admiring for months in Clarks window. I've never had a pair before because of my humungous (sp) cankles but there was 50% off so I went nuts and bought them!!! They're a wee bit tight still but will stretch a bit as they're worn in i think (and hopefully my cankles will eventually slim into seperate calves and ankles?!).
Thanks everyone for your input - you are fab!
