Hailey Bieber Dazzles in Silver Strapless Slip Dress

Hailey Bieber stepped out in a little metallic number last night, and while some have compared the ensemble to that of a tube of her beauty brand's lip balm, we personally think this may be one of her best looks yet.

Joined by her husband, Justin Bieber, the two were photographed at her Rhode UK launch party hosted by the Chiltern Firehouse in London on May 17.

The 26-year-old model looked stunning in a chic, silver strapless slip dress by N°21, matching pumps and a small black handbag. She took her sparkle to a whole new level by finishing off the look with a classic smokey eye, a peach lip, statement earrings and just her wedding ring.

Justin, 29, on the other hand, opted for a more casual look–pairing a green pair of Vans sneakers with baggy khakis, a white shirt and a green zip-up hoodie layered underneath his oversized black leather jacket.

Wednesday's event commemorated the official launch of the Rhode Beauty cosmetic line in the United Kingdom, and as the founder and creative director of the company, Hailey clearly had the full support of her husband, who was later seen snuggling up to her during the event.

Other big names photographed celebrating Hailey and her brand's success at the big launch party include Sabrina Elba (the wife of actor Idris Elba), British race car driver Lewis Hamilton, London-based celebrity stylist Georgia Medley, POOSH contributor Roxie Nafousi, fashion and beauty blogger Uche Natori, among many others. Notably, none of the members of the Kar-Jenner family appeared to be in attendance.
