Matthew Williamson is a mama’s boy! The recent H&M collaborator cites his mother as his first muse.

The British designer, who has worked with stars including supermodel Kate Moss, Madonna and Gwyneth Paltrow, says his mother’s flawless look motivated him to enter fashion.

He explained to VogueTV: “I think my first fashion moment was watching my mom prepare for work. She used to prepare meticulously the night before and I would sit at the edge of the bed and question her. She was a little bit like my first muse.”

Matthew has since been inspired by Jade Jagger and actress Sienna Miller. He has been vocal about his love of Sienna’s style, saying he admires the way she has adapted her look during the ongoing global financial crisis:

“The credit crunch means people spend on things they love rather than trends. Sienna Miller looks great because she’s not afraid to mix designer pieces with cheaper things. Iconic pieces are good buys at the moment. A brightly colored belt is my all-time tip—a cinched waist looks great on everybody. A pink patent-leather studded belt transforms a T-shirt dress from being casual and beach-y to a glamorous silhouette.”
