How to act like natasha romanoff 
Be at ease with yourself. 
Natasha is generally a very confident, easygoing, firm woman, with the ability of dry wit and humour. You don't exactly have to radiate charm, but try loosening up a little and being more confident-although not to the point where you're offensive to anybody.
She is also a bouncy, sprightly woman, and very mature, so attempt to work these things into your manner. Don't go over the top-try to be subtle and mysterious! Be stealthy.
