Lili Reinhart gave Old Hollywood glam vibes in the fiery red floor-length gown from Valentino. The Cady Couture Long Dress featured long, tailored sleeves and a high draped cowl neck wrapped around her collar. The complete coverage at the front offset the dramatic open-back design. The huge V-shaped cutout at the back plunged all the way down to her waist.

This stark, geometric open back added a sultry element to what appeared to be a simple red dress from the front. Furthermore, the fabric draped down to a floor-sweeping length, gathering at the lower back before falling into a graceful, rounded train that pooled around her feet.

The lower half of Reinhart’s look was not visible in the photo, as she looked over her shoulder in the shot that captured her from the side for ELLE.

The “American Sweatshop” actress paired the red dress with Valentino Kabarett Earrings in Metal and Crystals. The oval aluminium jewel design was covered with crystals. In addition, pendant tassels composed of crystals and Swarovski pearls fell downwards from the top of the oval structure. The earrings added just the right amount of sparkle to her look, although her hair partially veiled them.

Reinhart wore her long blonde hair down in voluminous waves which cascaded over her shoulders and framed her face beautifully. Her makeup featured glowing skin, warm eye shadow, pink blush on her cheeks, and a glossy pink lip. Her upcoming movie, “The Love Hypothesis,” will premiere on Prime Video on September 23.
