Jennifer Lopez took her look to new heights on last night's episode of American Idol. Donning an off-the-shoulder long-sleeve dress with perspex embroidery by David Koma and metallic Casadei pumps, J.Lo polished the look with a super sleek (and sky-high) topknot resembling a work of art.

And as much as we couldn't take our eyes off her outfit, we also found ourselves fixated on her nails. "Tonight we really wanted a super high, reflective metallic silver to play off the mirrored accents along the neckline of her dress," nail artist Tom Bachik told InStyle exclusively. "Once we chose that polish for the nails, she chose jewelry and shoes to play off the color and made her nails pop even more."
