Portman also revealed she developed an interest in perfume from her mother and believes it is important to include scent when "dressing up".
"My mum taught me to spray fragrance and walk into it. She has a sensitive sense of smell, so I've grown up with a great awareness. A scent that sets you apart makes you feel glamorous and elegant and gives you a different way of walking into a room - it's part of dressing up," she added.
