The designer, who met the actress through her hair and makeup team, was called about a month ago to work on a design for Meryl's double-nomination at the Globes. "I wanted to faint!" Chris tells People about receiving the call. "I have always wanted to design something for someone like that, and it was a great and amazing opportunity." Soon thereafter, Chris met with Meryl to discuss his vision. "I liked the idea of putting a belt on an evening gown -- I think it gives [a gown] a modern twist. I sketched it out quickly and she really liked it," Chris says. And while Meryl might be one of the biggest stars in Tinseltown, Chris says meeting her was anything but intimidating. "She is the sweetest person you can imagine. She's very friendly and welcoming and I wasn't nervous at all."

After turning out Meryl's dress in under a month, all the hard work paid off when Chris watched the Julie & Julia star take the stage to receive her Golden Globe for best leading actress. "I almost had a heart attack when Colin Farrell read her name. It was very exciting to see her come up on stage wearing a dress that I made with my own two hands," says Chris. "I thought it made her look tall and thin and comfortable and confident. It looked great!"
