Best Dressed

Taylor Swift: The "Bad Blood" singer dazzled in a white Balmain jumpsuit featuring a classy, low-cut plunge and revealing cutouts. "The diamond cutouts themselves remind me that I should just leave that bagel alone," Mai said.

Kendall Jenner: The 19-year-old fashion model turned heads in an oversized Balmain jacket paired with skinny pants. "The plunge was tasteful, the sleek, straight hair tucked behind the ears - this was a very fashion forward take."

Celine Dion: The GRAMMY winner topped Jeannie's list, calling her the "fashion queen reigning supreme." All eyes were glued to Celine from the moment she strutted onto the stage in a green leather Mugler minidress.

Worst Dressed

Britney Spears: The pop diva missed the mark by Mai's estimation. "I felt it didn't show off her shape," Mai said of Spears' long-sleeved dress. "I felt it wasn't as young as Britney is. It kind of looked like a fisherman lost his net at sea and Britney found it and decided to drape it around her body."

Kylie Jenner: The youngest Kardashian sister unfortunately was Mai's least favorite. "It was something that just looked like it wore her down the red carpet," Mai said.
