Over-the-knee boots

Over-the-knee boot
Adam says the over-the-knee boot is the hottest style of the season. "It's back. Remember we had these in the '80s?" he says. "You want to wear a flat one because if you wear a heel one it's a little too Pretty Woman."

Adam says to match the color of the boot to your tights, leggings or pants. "They can make your legs look longer and leaner if you dress tonally," he says.

Buckle boots

Buckles are a great way to warm up your winter wardrobe. Adam says they're available in every height and style. "You can find these flat, you can find these lower, you can find these as a high boot," he says. "It's a great way to add a little edge to a black pant or simple outfit."

Slouchy boots

Slouchy boot
Channel your inner Pat Benetar with modern, slouchy boots. If you're lean, you can wear them with a skinny jean or a legging. If you're a little curvier, Adam says this boot will look great with a knee-length skirt. "It will camouflage a multitude of things," he says.

Corset boots

Corset boot
The peep-toe, lace-up boot is a sexy take on the traditional boot. Adam says women of every age can embrace this trend—wear it with wide-leg pants for an office-appropriate look.

The best part of this style? The lace-up corset makes every foot look narrower. "It makes your foot look longer and thinner," he says.

Riding boots

Riding boot
For a classic look, Adam says a riding boot is a great go-to—especially in gray. "Everyone likes a riding boot," he says. "Gray is very big. It's big in boots and big in clothing."

Have trouble finding boots to fit your calves? Adam has the perfect option for you. "These are extra-wide boots from J.Crew—the best boots out there for a wider calf," he says.
