There's pretty much no logic involved when guessing a girl who got a campaign. Especially with Dior. John can love someone as much as possible, make her open or close 20 shows and even then that would not guarantee a campaign. Look at Michaela K, Irina K, Georgina, Morgane, Olga, Charlotte, Viviane, Tatyana etc etc. All obvious runway favorites and some for over five years now (Morgane! Linda V!) and still no campaign, so....
I don't see any chance for Sigrid to get it though....she's too new. I'm preparing myself for another Gisele or Kate borefest....
