The LBD is a classic, and this week's red carpets saw a lot of creative takes on the tried-and-true frock.
Julianne Hough, 26, rocked a modern, on-trend take on the classic LBD in a slinky black dress with cutouts. The halter neckline and symmetrical design, paired with the midi hem lenght, kept the look from being tacky. The "DWTS" judge paired the sexy dress with red lips, classic curls and simple black pumps.
Hough wasn't the only one rocking the LBD this week. Taylor Swift, 24, opted for a mod-inspired sequined mini-dress with a high neckline, and Heidi Klum, 41, turned heads in a lacy strapless cocktail dress.
