>> My dear friend susie_bubble just got her hands on a pair of the Prada knee high stockings -- I have so got to get me a pair. I thought you all might be interested in what she had to say about them since we were trying to figure out how they stay up by themselves a while back. (They come in black and gray, £55.)
They are actually tight but also very very long so you get the ruched/bunched up effect.
When I studied the Prada catwalk pics, I realised that they weren't actually all that loose on the models either but just bunched up because of the length. The size of the socks corresponds to your feet size as opposed to the size of your calves/thighs.
They feel very nice against your legs.
