1. The side-shave.
Skip shaving the side of your head this year and instead, curl your hair to achieve all-over volume, and then tuck one side behind your ear for a sleek look.
2. Forced waves.
Really done-up hair can look contrived rather than effortlessly cool. For a more current take on curls, opt for unpolished bends (seen at the Narciso Rodriguez show), which you can create with a flat iron.
3. Noticeable contouring.
This year it's all about subtle contouring, which will give you a more natural outcome and still sculpt your cheekbones to perfection. For a tutorial on the right way to shade your face, click here.
4. Fan-like lashes.
Amping up your lashes is a surefire way to draw attention to your eyes, but it has to be done the right way or else your fringe ends up looking really fake. To make sure your lashes looking natural instead of like a fan, apply several coats of mascara, waiting a minute in between applications so the formula properly adheres to the coat before it. Or use individual falsies, or cut a lash strip in half and apply it to the outer corner of your eye only.
5. Overdrawn lips.
If you have super-thin lips and want to create a larger look, then follow this tutorial by Jessie James Decker. Otherwise, if you already have an Angelina Jolie-like pout, stick to a barely there nude lip or just use balm, since a light pastel shade makes lips look plump, and the last thing you need is for your lips to not be proportionate to the rest of your features.
6. Super-dark smoky eyes.
It's always more flattering when a smoky eye has dimension, rather than jet black from your lash line to your brow bone. To make sure yours is multi-dimensional, pick up a no-fail palette that includes all the colors you need to pull off a sexy, subtle smoky eye, like Happy Skin's All Eyes On Hue Eyeshadow Palette.
7. Insanely long extensions.
This length is perfect for pulling off an Elsa-inspired side braid, but this year it's all about texture and short, chic cuts, so take a cue from T.Swift.
8. Sharp and boxy Pinterest brows.
You know what they look like: They're overly filled in and squared off at the beginning, and look like they were drawn on with a stencil. Makeup isn't geometry class! Your brows should always look feathery and lightly colored in, so they leave you looking youthful and fresh-faced, rather than harsh and fake. See: any picture of Cara Delevingne.
9. Lavender locks.
Pale purple has had a long reign, but in 2015, it's all about jewel-tone shades that mimic a dark, almost-natural shade.
Bye, ombrè. Baliage (painting on highlights for a more natural, sun-kissed finish that grows out beautifully) is back, proving to be the prettiest way to color your hair in 2015.
11. Eagle talon tips.
Whether nude or colored, almond-shaped nails need to stay in 2014. In 2015, file your nails into a shape that mimics that of your cuticles for a more natural look.
12. Highlighter overload.
This coming year feels like the perfect time to stop shining spotlights on your face with excessive amounts of white shimmery formulas. If you want your brows or cheekbones to pop, use a pink champagne (for fair skin tones) or rose gold highlighter (for medium to dark skin tones)—or even a concealer that's one shade lighter than your coloring. Or, better yet, skip patting on any highlighter for a gorgeous "I woke up like this" look.
13. Crazy graphic liner.
Let's be honest, you're not wearing this out with your guy on Friday night. But don't worry, the liner looks for 2015 are more wearable and therefore sexier.
14. Black lipstick.
Since black lipstick is actually pretty difficult to pull off, stash your black bullet (if you ever purchased one when it was trending last year) for berry-colored or red lip color, like Bianca's, which complements all skin tones.
15. Oversized buns.
Gone are the days of inflated buns (hopefully!). This year, dainty, sophisticated, and low buns are all the rage.
