Selena Gomez looked phenomenal in four very different outfits while in New York City to promote her new album, Revival.

The 23-year-old took the streets by storm on Tuesday, rocking outfits in the black and white color scheme.

But the most sultry ensemble by far was a knitted turtleneck crop top, which Selena opted to not wear a bra with, teamed with a slit-to-the-thigh skirt.
