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.
