The 78-year-old said the pleated muslin and organza dress with a ruffled collar was "perfect" for the pregnant bride.

"I love her. She's great," Lagerfeld said at Wednesday's opening of an exhibit celebrating Chanel's signature Little Black Jacket, which was curated by Lagerfeld and former French Vogue editor Carine Roitfeld.

"I think she looked beautiful and it fit her strong personality," he added to InStyle.com.

Barrymore, 37, married art consultant Will Kopelman on June 2 at her home in Montecito, Calif. Guests in attendance reportedly included Reese Witherspoon, Cameron Diaz, Jimmy Fallon and Busy Phillips.

Lagerfeld says he's known Kopelman, the son of former Chanel CEO Arie Kopelman, since he was a child.

He said he and Barrymore tried several options before settling on the custom gown featuring feathers, embroidered flowers and a black satin belt.

His advice for dressing up with a baby bump?

"Be comfortable, even in the wedding dress," he said.
