With a crop top design and an A-line short skirt, she asked fashion house Roberto Cavalli to make three identical outfits in different colors, corresponding to three different Christian Louboutin glitter shoes. Photo: Roberto Cavalli

Cavalli’s designs include three color pairs: pink – blue, green – red, orange – purple. All are processed with ombre and glitter techniques, creating eye-catching effects on stage. Photo: Roberto Cavalli

When performing gentle ballads, she wore a fuchsia cut-out dress by Alberta Ferretti. Photo: Ferretti

Similar to the sequined gown, Roberto Cavalli also prepared three mullet dresses in soft, pleated silk dyed in ombre. All three were treated to vibrant colors of orange, pink and navy, combined with classic silver shoes from the 1920s by Christian Louboutin. Photo: Roberto Cavalli
