A belt truly is the MVP of fashion accessories. It can accentuate a little middle, add curves to an athletic figure, draw the eyes towards your, ahem, assets, and even work well on swimwear.

But there's one place you might have never thought to utilize the versatile accessory: winterwear. “Sweaters and coats can be so bulky and oversized that your figure gets lost in the added volume and thicker fabric,”  explains Argy Koutsothanasis, a stylist whose clients include The Bachelor's Jojo Fletcher and Becca Tilley. “A belt is a quick and easy way to cinch a thick sweater or puffy coat so that you give your shape some definition.”

Not sure how to pull off the look? Koutsothanasis says it's all about playing with what you've already got: “The trick is to select a style that works with your body and proportions. If you have a small waist and curvy hips, you can wear a larger belt to really accentuate your tiny middle. If you have a fuller or straight up-and-down torso, you can pick a thinner belt so as not to add volume to your middle.”

Her only rule? Pay attention to where you place the belt—on the natural waist or on top of the hips are the two best positions; anything too high or too low will just look awkward.
