Both Sailor Brinkley Cook and her mom, 65-year-old Christie Brinkley, strutted their stuff on the Elie Tahari runway, proving that the same line, the same clothes, can be fitting for a wide age group. "Sailor and me on the same runway ! We're on a HIGH...Five✋🏼🖐🏼Thank you @elietahari for the honour of walking in your 45th anniversary show! But there was NO WAY I could keep my game face on ...when I saw my daughter strutting the runway I could not do anything but Smile! Thank you Eli for this," Christie wrote underneath a video on Instagram, proving that there's an emotional tie-in to a strong collection that binds women together.
