Both ladies looked stunning at the store's celebration, plus they were there for an especially good reason: the ribbon cutting was also a benefit for Life's WORC Family Center for Autism and the North Shore Animal League America, two non-profits on Long Island.
The mother-daughter duo stuck close together, posing together in front of a bright wall covered in pink, orange, and white roses. Sailor opted for an olive green slip dress, which she paired with a silver choker and black knee-high boots, while her mom literally shined in a metallic pleated dress, black blazer, and glittery gray pumps.
Adorably, Christie couldn't stop beaming at the event!
The pair were clearly excited to have a girls' night out, flashing mega-watt grins in a pic the 62-year-old model shared on Instagram after the event.
It couldn't have been tough to be in a good mood with these adorable puppies around, though!
Sailor, Christie's daughter with ex-husband Peter Cook, posted a shot as well, though hers was of the two being interviewed, and graciously thanked the evening's hosts. "Thank you for a great night @lordandtaylor supporting autism awareness and the @animalleague and the opening of Lord and Taylors new amazing store in Garden City! Thank you again for having us!" she wrote.
Christie, a longtime animal activist, shared a Maya Angelou quote via Instagram...
...before requesting a call-to-action from President Barack Obama. "I'm calling on @POTUS to do everything in his power to safeguard our climate and communities before Donald Trump takes office," she tweeted.
