Terri Irwin took to Twitter to congratulate her daughter, Bindi, on the recent nuptials to her new husband Chandler. In her tweet, she shared a photo of Bindi's brother Robert in Steve's arms -- where the father and son duo wearing his standard Khaki zoo suit.
"Remembering @RobertIrwin’s first wedding. I love that Steve and Robert both wore khaki. I know Steve would have worn khaki to Bindi & Chandler’s wedding, too. I wish he could have been there to see the most special day in his daughter’s life. We miss him so much," Terri tweeted.
