Straightforward and foolproof as it may seem-"Just pick something red and sexy!"-the business of shopping for a perfect Valentine's Day dress can be surprisingly tricky. Go too themey with a dangerously low-cut or heart-patterned design, and you'll never pick up said dress the other 364 days of the year; go basic with your standby LBD and, well, that makes your special V-Day date seem not so special after all.
Lucky wholeheartedly endorses the idea of dressing for the occasion-and in that spirit, we've picked out 15 knockout Valentine's Day dresses you're guaranteed to get major mileage out of-yes, even when it's not roses-and-chocolates season. A mix of red, pink and always-flattering black numbers, they're bound to work their way into your regular rotation. Click through above to shop them all!
