In case your invitation got lost in the mail, Madonna celebrated her 56th birthday this weekend with an epic, 1920s-themed rager in Cannes that brought out folks like Kate Moss, Riccardo Tisci, DSquared's Dean and Dan Caten and Mert Alas and Marcus Piggott. The night's tagline appared to have been "La Vie En Rose" and, to that effect, guests turned out in a mix of black tie and Weimar-esque cabaret looks (think: flapper dresses, straw hats, suspenders, fishnet stockings, lingerie, garter belts). We've gathered our 10 favorite Instagram shots from the night below and, in the words of Madonna Louise Ciccone, bow down to the #unapologeticbirthdaybitch.

10 years from now, a little kid is going to be playing in the beautiful waters off of Cannes and a giant, glistening 'M' is going to wash up in the surf, a long-lost memento from a night that was.
