For the DIY-inclined, a simple trip to the drug store for pins, stickers and rhinestones offers more inexpensive options.
"People are being super, super creative with nail art. ...They're really having fun," Barfield said. "Nails are a talking point."
Five trends for nails:
Got a thing for those red-soled Christian Louboutins? The shoe designer is hoping his fashionista fans will go for his first try at beauty — glossy, luxe nail lacquer that launched this month in his signature hue.
Rouge Louboutin, loaded with pigment that goes on easily, is priced at $50 for an eight-inch spiky bottle based on the tallest heel he ever came up with, the Ballerina Ultima. Thirty more colors are on the way.
Nails have become a growth market for designers: Phillip Lim and his 3.1 Phillip Lim brand have a new collaboration with Nars. Burberry opened its first beauty store, including polishes, in London's Covent Garden last year. Anna Sui, Michael Kors, Marc Jacobs and Tom Ford are all recent entrants.
Prabal Gurung works with Sally Hansen and Brit "it" girl Alexa Chung came up with fabric-inspired finishes for London-based Nails Inc. Her bottles include a cashmere look and heavy glitter options.
Louboutin's lacquers are the most expensive for a major brand.
"Obviously the Chanels and the Diors have been doing nail polish forever, but what's great about Louboutin is there are so many women who love his shoes but might not be able to afford them. It's a way of getting a piece of the brand," Barfield said. "The bottle is like a piece of art. He wanted it to be something that looked beautiful on a woman's vanity and on her fingers."
Ciara, Beyonce and Adele have all blinged out the underside of their nails.
"It's kind of like a peekaboo. It's unexpected. The long, almond-shaped nails are really big right now, so they allow enough real estate for you to embellish underneath your nail," Barfield said. "This is a new twist on nail art, which is such a big trend right now. You don't have to get this done. You can do it yourself at home."
Attach a small jewel or stud with spray glue, or go for bright colors that complement the front side.
