Heming, who raises two daughters Mabel, two, and one-week-old Evelyn with Bruce, 59, said she has no influence over his wardrobe, reported Hello! magazine.
"I have zero influence on Bruce and his style. He knows what he likes and what works for him. He's not fashion-conscious and I'm happy about that. He puts it all together very well," Willis said.
Emma, a former model, said she is happy to have focused on raising her children with the 'Die Hard' actor.
