The 33-year-old actress already has two children, both sons, but she said that she keeps all her favourite gowns in case she and fiance Matt Belamy add a little girl to their brood, reported Contactmusic.
"I archive a lot of my pieces - from when Stella McCartney was at Chloe and Tom Ford at YSL and Gucci. My mum (actress Goldie Hawn) never kept her clothes. She was big into (Azzedine) Alaia clothes and she didn't keep them," Hudson said.
"She also had Ossie Clark dresses from the '70s, and I never got to wear them, so I decided when and if I have a little girl in my life, maybe she'll be into them and want to go into my closet someday," she added.
