Katy Perry during top 5 of idol
Dark Lady
4 / 13

For Idol's Mother's Day episode, Katy gave off major Cher vibes in this vintage-inspired multi-colored sequin halter dress with cold shoulders and diamond cut-outs along the waist, which she paired with Sara Weinstock cushion drop earrings and a white-gold EFFY Jewelry diamond ring. She finished off her look with a black center-part wig, bronze eyeshadow and a pink lip.
