>>595 Fashion week isn't over yet. Anyway, EO can't decide to attend a fashion show, generally it's the brand that sends invitation, and pays - though big names are likely to get one if they ask and her sisters certainly help. And they don't always invite the same name, unless that particular celeb is linked to the brand.

As for the possible explanation of her maybe absence, kind of a moot point, don't you think? There's no way of knowing for sure so there isn't much we can say.
