Middleton, 35, gave birth to a baby boy on Oct. 15, her first child with husband James Matthews.

"Everyone is delighted and Mother and baby are doing well," a rep for Middleton said at the time.

Though Wednesday marked her first official appearance since becoming a mom, Middleton was previously photographed with her husband in early January during a vacation in St. Barts.

On the same day Middleton attended the London gala, her sister Kate made her own fashion statements with a bold red coat and later a mint green dress during a visit to Northern Ireland.
