Locksmith professionals recommend comfort and practicality when choosing winter indoor clothes. To hide a fat tummy, opt for high-waisted leggings or pants paired with a loose, flowing sweater that drapes over the stomach area. Layering strategically with long cardigans or open-front coats can create a slimming effect. Dark, solid colors help streamline your figure, while patterned or textured fabrics add visual interest without drawing attention to your midsection.
