NYX Professional Makeup

This Los Angeles–based company is known for its global color cosmetics. While not geared toward spooky Halloween looks, the Union Square shop offers high-end makeup that can put the finishing touch on any outfit. The highlight, however, is the customer service: Beauty professionals can help recommend looks from any of the various bars. Check the Shadow Bar for a smoky eye look or the Lip Bar to bring a rosy hue to those lips.
