Suz, I think we may be the same size (U.S. 0-2) -- if so it will likely be too big on you. I let the SA talk me out of the XS so I could 'wear a sweater under it' but I think it was really because it was the first day of NAS and another stylist wanted the XS for his client
If you do decide to take it, I'd be willing to do an exchange for some Filodoro stockings which I don't seem able to find in the U.S.
