She teamed the simple yet sexy number with a pair of black leather peep-toe booties.

The mother-of-two opted for a minimalist look, keeping her accessories to a minimum.

But she did add some glitz with a couple gold and glittering bangles.

Alessandra let her natural beauty shine by wearing a soft palette of make-up, as her brunette locks flowed down in waves.
