With Sheryl Crow in the house to mentor "American Idol's" remaining five contestants, it's no surprise Haley Reinhart and Lauren Alaina took the stage looking rocker chic.
Ladies' costume designer, Soyon An, discovered a new fashion boldness in her young charges trying to sing their way into the upcoming finals.
Alaina, 16, told An she wanted to "look fierce" for her first number; singing Carrie Underwood's "Flat on the Floor." "And Haley just wanted to rock out and look chill," An says.
Here, An gives us some of the week's style high notes:
Alaina: "She's finally gotten to a place where she feels confident enough to wear a high dramatic boot and I went for it," says An. "I think the entire look, helped along by the boots, lengthened her and slimmed her out. She's got a tiny, size four waist and looked amazing. Lauren told me, "I want to do Carrie Underwood meets Rihanna." She was ready for anything I threw at her this week.
Alaina's first look included those Report Signature boots, a chain dress by Sheri Bodell, a dramatic Fiona Paxton bib necklace, Mint Collection cuff, waist-cinching BeBe belt, a white dome ring by Kitson and Wet Seal earrings.
Her second performance, "Unchained Melody," needed something more romantic and Alaina took her stylist's advice to slip on a floor-length blue-and-white dress with cut-out waist detail by Tony Bowls. She accessorized with Chinese Laundry wedges, Neon Dirt earrings and blue flower ring from Wet Seal. "We were looking at a black mermaid-style dress but the way she sang that song was so enchanting I wanted her too look like an angel," An says.
For her showstopping performance of "House of the Rising Sun," Reinhart wore Domino jeans with paint-splash details, a feathered, flowing top by Meghan, earrings and a necklace by Saint Vintage designs. She also stuck with the same bracelets from her first act.
"She very much wanted to be comfortable for this performance and she nailed it, so I think that comfort was key for her," says An.
The Guys: If you pay close attention to the accessories of front-runners James Durbin and Scotty McCreery, you may notice their fondness for sterling statement pieces. (For Durbin it's a feather-motif dangle earring, for McCreery a prominent cross on a neck cord.)
These personalized pieces were custom-made for all the Idols in collaboration with artisan Tim Foster of Pennyroyal Silver, who has been working with Idol contestants to create personal keepsakes for three seasons.
