Seyfried, for her part, wore a body-contouring black dress by Giorgio Armani that fell to the ankle, with thick straps that traced into a plunging neckline. She styled it simply with black Jimmy Choo pumps, gold rings, a delicate gold bracelet, and a gold chain necklace. Her makeup was kept super minimal and fresh and she wore her nails bare, with her blonde hair styled loose and tousled.

Both Selena Gomez and Amanda Seyfried stayed true to their own schools of style: elegant, polished, sophisticated. Where Gomez will often opt for pretty and feminine dresses by Doen and Danielle Frankel, denim by Khaite, and MaxMara outerwear, Seyfried is regularly swathed in Versace suits (via Julia Roberts!), Marc Jacobs tailoring, and structured Valentino looks.

As proven by both women, there’s so much to play with when it comes to a classic LBD. Choose your festive-season fighter.
