I'm not sure where these are from, but I've seen quite a few shoes around with a pencil heel like this.
Although on closer inspection, don't these look a little big for her?!
Being of a small stature (5' 2.5" - the half matters) I often think I should live in heels, but even on nights out I'm usually in boots or flats. Perhaps if I had a pair of Louboutins I could be persuaded.
