I was trying to think just how long she has been wearing the toe post/ legging combo, but I can't remember. Anyone else hazard a guess? I reckon she'll hang on to them until they drop to bits. After all, they are a recurring topic on here and we all know how much HM likes to be kept in the spotlight.
She hung on to the blue jacket from the start so doubt she will lose the them anytime soon. If she only wore ordinary leggings and sandals instead of them she would look so much better.
