Check out who is rocking killer threads and who needs to put their stylist on (permanent?) timeout this week.

Best: Celine Dion

Celine Dion looked positively ageless as she showed off her legs on “Late Night with Jimmy Fallon” on Monday (Oct. 28). The singer opted for an edgy black number from Anthony Vaccarello’s Fall 2013 collection to promote her new single, “Loved Me Back to Life.” Dion styled the feisty one-sleeve dress with killer black pumps, a bold silver ring, a pink lip and wavy tresses. We’re totally having major Dion hair envy here. Kelly Rowland and Anna Dello Russo both recently stepped out in a similar look from the designer, but we have to admit, Celine rocked Vaccarello’s threads best!

Worst: Mariah Carey

We wish Mariah Carey left more to be desired while honoring Patti Labelle on the “BET Black Girls Rock! 2013” stage held at New Jersey Performing Arts Center in New Jersey on Saturday (Oct. 26). The singer hit the stage in a black crop top paired with a floor length Alexander McQueen Resort 2013 black skirt complete with gold embellishments. First, not to be nitpicky, but Mariah already wore this skirt on “American Idol” last year. While repeating a skirt isn’t complete fashion suicide, we have to say, this look does nothing for the singer. In fact, it’s downright unflattering.
