Your ear warmer should be a fashionable accessory that works with the rest of your clothes. When choosing an ear warmer to wear, select one that will match the colors you're wearing. While picking the same colors works, it's not the only way to coordinate your colors. Make sure that your ear warmer and clothes stay within the same family of tones.   If you wear earth tones, make sure that your ear warmer is also earth toned. If you like loud and fluorescent colors, make sure that you get an ear warmer that matches it. Families of color include pastels, earth tones, or jeweled tones. Another easy way to coordinate your colors is to look at a color wheel and find a complimentary color, or a color that lies as a direct opposite on the wheel. Opposites on the color wheel include greens and pinks, yellows and violets, and reds and blues. Consider the look you are trying to embody and choose an ear warmer that goes along with it to keep your overall look cohesive. For instance, if you are trying to go for a sporty look, a sports headband ear warmer would probably look best with a sporty outfit. If you're going for a casual or chic look, a knitted ear warmer in earth tones will work best. Ear warmers draw attention to your face and give you a more casual look and style. Put on subtle wintery makeup hues and keep your makeup as minimal as possible. Things like flashes of white highlights and minimal eyeliner will work best with an ear warmer. Wearing a scarf, beanie hat, or hood can help compliment your style when wearing ear warmers and will also give you better coverage over your head and neck. Wearing these things together will trap in heat and keep you warm, even when it gets cold out. Think of how your ear warmers coordinate with the rest of your clothes, like your winter jacket and gloves. Shawls look good with knitted ear warmers.
Consider the color. Pick an ear warmer that matches with your outfit. Keep your makeup subtle. Coordinate your wear warmers with hats and other winter accessories.
