the age issue
I dig Isabel Marant (that's where the above dress is from), just one of the many French "mid-range" designers doing perfect, simple things I can't afford (think Vanessa Bruno, A.P.C. etc).
Anyway there has to be something like a 20-year age difference between Geraldine Saglio (of French Vogue) and Julianne Moore (no introductions needed), so it's rather cool to see them rock the same dress so well (although to be fair, Ms Moore is not a normal 48-year-old).
It's always been a thing of mine to wonder whether I can wear that same thing when I'm 40 whenever I'm out shopping. So the idea that one simple tunic dress can be worn so well over a 20-year age span is my idea of heaven.
