I don´t have anything againts the hairdo on Gisele, maybe it is just me but she looks a little kate moss-ish, but as you say, why to make the collection even more accesible trough simple styling, there was such little drama on the catwalk to begin with that this is simply not enaugh for fashionistas.
Although comercially speaking it is more likely to catch women´s attention alluring them with a simpler image like this, they now don´t need to be a fertility goddess to carry the Dior summer 09 look, they only need to be similar to Gisele..., which isn´t at the end a sort of modern fertility goddess anyway?...
