Allie MacKay of KTLA in Los Angeles was with singer Caitlin Crosby to show off the latest fashion trend that helps out an important cause, the Giving Keys. “I started paying a locksmith to engrave inspiring words on these old used keys,” Crosby said. “I really wanted it to go to charity and have its own special twist. I ended up meeting Rob and Sarah who lived on the streets and” then had an epiphany where she thought they could make the keys. “I wasn’t thinking about the Giving Keys when I met them, I just loved them and loved their story. Basically I was like how about you guys be my business partners? I started paying them to engrave the keys.” Crosby says that after wearing the keys, people are encouraged to pay it forward and give them off to someone else. Watch the segment via KTLA.com below.
