Many women hesitate to wear long gowns, believing that the sophisticated frocks are simply too dressy for a night out. So we're happy to present a straightforward solution to this sartorial dilemma: belted gowns! From skinny metallic iterations to thick, low-slung versions, belts have the ability to ground fancy duds and make them skew a little more casual. We gathered several stylish examples from designer runways and the red carpet, including a monochromatic look a la Jessica Chastain and a glam bohemian getup like Rachel Zoe's. No matter what rendition you choose, these waist-cinching accessories offer a flattering way of reining in a voluminous gown and accenting your midsection, so buckle up for this brilliant eveningwear trend today!
