Season after season, makeup artists reinvent the classic cat eye, and the fall 2016 shows were no different. At Marc Jacobs, Francois Nars used practically every black eyeliner in his kit to create elaborate eye makeup looks, the most wearable of which was this open, almond-shaped outline. At Oscar de la Renta, Diane Kendal used M.A.C. Creme Liner in Black to create a similar yet subtler version of an open, squared off oval. And Val Garland used the same black liner at Monique Lhuillier to create a thick, blunt edge above the upper lashes.

Black lipstick is back, but for fall 2016 you'll want to layer red or berry over black. Backstage, makeup artists tapped the color on with their fingers for a lived-in, stained effect.

Shades varied from plum at Zac Posen to berry at Naeem Khan (Maybelline Color Sensational The Loaded Bolds Lip Color in Smoking Red -- launching in June) to burgundy at Rodarte (Nars Audacious Lipstick in Liv).

Matte top coat is having a moment. Backstage, it was layered over bare nails, neutral nails and muted tones. And some nail artists even used it selectively on just one or two nails for a very subtle take on the accent nail. Backstage at Narciso Rodriguez, manicurist Deborah Lippmann said, "a matte top coat can take an otherwise chic nude nail and transform it into edgy elegance."

To try the trend, pick up a bottle of Essie Matte About You, JINsoon Matte Maker, Nails Inc Westminster Bridge Matte Effect Top Coat or Deborah Lippmann Flat Top Mattifying Top Coat.

Extremely simple yet pretty nail art -- often on bare or nude nails -- was all over the fall 2016 runways.

At Tracy Reese, Jamberry created custom nail wraps inspired by the collection (they're available now), the coolest of which is called "Urbanite" and features basic black stripes on a clear background.

At Jenny Packham, manicurist Michelle Saunders used Essie Mademoiselle as the base and drew gold stars on the thumb and one other random nail using Essie Good as Gold. "Just a bit of nail art, done elegantly, can be another form of accessorizing," she said.

And at Tibi, Jin Soon Choi was inspired by the military accents in the collection and drew a simple military insignia in a muted gold tone using JINsoon polish in Cachet.
