Repetto ballet flat in red patent

Repetto ballet flat in red patent, $295, saksfifthavenue.com.

In 1956, the French company Repetto answered Brigitte Bardot’s call for a pair of flats that were as comfortable as ballet slippers—et voila, the ballet flat was born. To celebrate Bardot’s 80th birthday this Sunday, I’ll be wearing this classic pair in red patent leather. And feeling grateful.
