Jennifer Lopez's best 'American Idol' fashion: Risque blue dress or peachy pantsuit?
Host Ryan Seacrest seemed to love the look the returning judge sported for the Top 10 girls performance show, but the low-cut top and short length made some waves on Twitter -- the sparkly getup wasn't exactly appreciated by everyone.
On the second live show, when the Top 10 boys performed, Lopez picked a much more demure look. The peach-colored pants ensemble with an off-shoulder neckline and wide-legged, flowy pants was both fashionable and classy. Which look did you prefer? Vote in our poll.
