The evening commenced poolside with sips of cocktails and bites of hors d’oeuvres as a local Mariachi band performed.

Lauder, who was dressed in Raquel Deniz, mingled with Kelly Klein and Lauren Layne Merck.

Lauder had invited her favorite hat designer, Sarah Bray-West of Sarah Bray Bermuda, to create custom hats.
