The realty beauty oozed chic as she swapped the slinky bodycon and vibrant reds for something a little prettier - and we most certainly approve!
Casey proved that florals aren't just for spring as she made her debut at the bash in this metallic bloom adorned frock from Comino Couture, that boasted a tulip-style skirt and a ruffly blush coloured body.
Like Stephanie Pratt - who's outfit you can snap up here, FYI - Casey teamed her sweet little number with pointed court heels but toughened the look up with a black waist belt and matching talons.
As always, Casey's tresses were seriously on point and her huge bouncy blow-dry blew all of the other guests out of the water. Just look at those gravity defying curls!
The stunner was all smiles as she posed hand on hip alongside her mum, who she brought along as her +1.
