Jennifer Lopez has proved throughout her career that she can pull off just about anything and look flawless. On last night’s episode of American Idol, however, she threw us for a loop with her vibrant pink romper, leaving us with mouths wide open in awe and a desire to add a onesie to our wardrobes, stat. Hello, springtime. Nice to meet you.

“We went for a fun summer look tonight,” stylist Rob Zangardi told InStyle.com of the inspiration behind her outfit. “We dressed up the colorful pink romper with gold statement jewelry and gold heels, complimented by her loose, wavy hair.”

But apparently we’re not the only ones that loved her look. Her solid roll-tab crepe jumper from her namesake collection for Kohl’s was such a hit, it’s already sold out in pink online (but is expected to be restocked again soon). Meanwhile, you can scoop up the black version ($36 at kohls.com) to whet your fashion appetite.
