She may have left us with a serious case of outfit envy the night before (thanks to that trendy crop top), but on last night’s American Idol, Jennifer Lopez traded her pale-hued skirt and top for a more classic style—this vibrant red Lanvin dress.

To complete her look, hairstylist Lorenzo Martin wanted to spice things up by playing off of the crimson shade. “The red dress was reminiscent of an Italian beauty, so we created a sultry look with a half up half down hairstyle,” he tells InStyle.com.

The finishing touch? Her mani, which was also customized to blend in with the overall theme. Nail expert Tom Bachik made a custom rose gold polish to match the skin tones that her red dress brought out.
