Olivia Palermo at the Mango Show

As representative and model for the brand, Olivia Palermo was at the Mango Resort Fashion Show on March 1.

Sticking with the long-skirt looks she's been wearing lately, Olivia wore a floaty brown skirt with a Mango shirt.

Co-ordinating with the skirt was a brown belt and going with the shirt was her Christian Louboutin snakeskin sandals (a brown version of them costs just over $1,500 at footcandy.com).
