We saw some discussions on threads trying to sort out whether the L'Instant Magic (see our review) ad features Bar Refaeli or Michelle Buswell. We do not have this information in the press release from Guerlain and so initially put Bar Refaeli based on another press source. Now that we have seen the TV commercial, it is clear it is not Refaeli in the TV spot but Buswell as indicated by You Tube and other sources. The printed ad looks a bit more like it could be Refaeli hence the confusion. I think also that it makes sense they would hire a taller model to wear this extraordinary gown (Buswell is 1,80 m vs. Refaeli is 1,74 m).
You can watch the sumptuous ad directed by Jean Bocheux,
