Similar to her friend Maddy, yet not quite in the same way, Cassie (played by Sydney Sweeney) wears revealing pieces, but hers are often in softer shades like pale blue or pink. Almost always baring a fair amount of cleavage, from a corseted top with hardware-embellished straps to a slinky blue House of CB Ruched Organza Mesh Mini Dress (£119), Cassie's looks are decidedly feminine and flirty.
