Elizabeth Olsen thinks her 'It girl' tag is an ''ephemeral thing''.

The 'Martha Marcy May Marlene' actress - the younger sister of Mary-Kate and Ashley Olsen - explained while the term has helped her launch her career, she wants to be an ''older lady'' when she retires from acting.

She said: ''I always joke that the term 'It girl' is such an ephemeral thing. And I'm really tying to have a long career until I'm ready to retire as an older lady.

''So for me, it's really nice that it has helped me kind of start my career and I'm so thankful that it got the attention that it did. Because now I'm in such a cool position of choosing really interesting roles.''

While Elizabeth admits she doesn't talk with her A-list siblings ''directly about work'', they do advise her on what roles she should take.

She added in an interview with iVillage.com: ''We don't really talk too directly about work. If we do, it's more just about, 'I'm having a hard time making a choice, can you help me out?' Just anything that you'd ask anyone in your family if you trust their opinions.

''But, really, all they've done their entire lives was work and they're really amazing workers. They're such strong women that have so many different companies to take over and run and it's just amazing to have those types of women in your family.''
