Petsch - who plays Vanessa's girlfriend on the hit show - was even her besties bridesmaid.
"Guests were greeted by chatty tropical birds, roaming oyster shuckers and botanical cocktails as they delved into the vast gardens," an insider tells PEOPLE of the party.
"The cocktails, delicately prepared by Craft Cartel, were spectacular… all served with rose gold accents, one of their feature wedding colours."
