12 Easy Fashion Resolutions to Keep in 2016

I Resolve to: Start Wearing Jewelry More Often

To get the most impact for your effort, go for a pair of statement earrings. Whether sculptural and gilded or shoulder-grazing and glitzy, they're sure to brighten up your face—and your day.

I Resolve to: Nail a Going-Out Outfit That's Sexy (But Not Too Sexy)

1. Take a break from body-con and select a loose silhouette that's got graceful movement. Runway inspiration: Proenza Schouler (far left)

2. A flash of leg brings sensual appeal to otherwise subdued separates. Runway inspiration: Altuzarra (second from left)

3. Opt for a semi-sheer blouse and pleated skirt to achieve lady-and-the-vamp status. Runway inspiration: Gucci (second from right)

4. Black lace is shorthand for seduction. Balance it out with breezy, casual shapes. Runway inspiration: Valentino (far right)

I Resolve to: Break My Neutrals-Only Habit

Fashion's new crop of left-of-center shades—think pistachio green or over-the-top Barbie pink—provides a dash of intrigue and irony with their vibrance. Style with plenty of slouch and an insouciant attitude for an eye-catching statement that doesn't appear inordinately eager.

I Resolve to: Find a Bag That Can do Both Work and Weekends

Aim for a semi-structured tote with a single standout detail, such as a charming print or soothing shade, to earn compliments from colleagues and friends alike.

I Resolve to: Adopt a Work Uniform That'll Get Me a Promotion

Wear red. The heat-seeking hue conjures qualities people admire in a leader, namely strength, passion, and power. Stick to streamlined silhouettes, like a sheath dress, to keep the tone office-appropriate, or inject a shot of the color via a crimson bag. Runway inspiration: Boss

I Resolve to: Hunt Down a Pretty Pair of Shoes That Don't Kill My Feet

When flats feel too frumpy and stilettos too painful, reach for kitten or block heels. Armed with sexy lace-up adornments and playful patterns, they make up for what they lack in height with major attitude.

I Resolve to: Put on Outerwear That's Genuinely Warm Versus Stuff That Simply Looks Good

No need to sacrifice your beautiful coat when it becomes arctic outside. To stay cozy and chic, just add a slim-fitting down layer underneath.

Shop the pieces: DKNY coat, $995; at Macy's, for stores see macys.com. Uniqlo jacket, $70; uniqlo.com.

I Resolve to: Invest in a Stellar Bag to Update My Look

Consider a pouch. You can be more daring with designs such as graphic stripes or glittery embellishments. You can stash it in your tote when you're not feeling it or need more room. Truly an instant pick-me-up.

I Resolve to: Buy Beautiful Grown-Up Lingerie

There's something so accomplished about a woman whose top drawer is full of silky, filmy bras and underwear. Choose sweet shades and lacy flourishes for a foundation that can go from day to night (wink, wink).

Shop the set: La Perla bra, $138; laperla.com. La Perla thong, $78; laperla.com.

I Resolve to: Sport More Dresses & Skirts in Cold Weather

Count substantial suedes and leathers as your toastiest options, which also tap into the current '70s trend. Fleece-lined tights and knee-high boots also make frigid temps more bearable.

I Resolve to: Get My Closet Under Control
