Sisters night out!
For the intimate charity event, the High School Musical alum, 33, donned a sparkly gold, high-low strapless gown by Michael Kors, styled with sky-high metallic platforms and statement choker necklace. Her 26-year-old sister also turned heads, wearing a striking red high-neck sequin number by David Koma, which she accessorized with strappy black sandals and an up-do hairstyle.
"All dressed up for a special night with @unicef and @luisaviaroma to raise funds for the kids affected in Ukraine and Syria," Vanessa wrote on Instagram," along with photos of the siblings posing in their designer dresses. "Ty @michaelkors for the custom dress."
In addition to the sisterly snaps, Vanessa shared a fun selfie with Michael from inside the star-studded party.
"I'm so excited for her. I love her," Vanessa exclusively told E! News at the recent Cali Cares charity fundraising dinner at Spago in Beverly Hills, Calif. "She deserves the whole world, and I just love a full-circle romance. It's so cute."
