Dakota Fanning is an adorably bossy big sister as she warns Elle 'that's my stuff!' in throwback Halloween video

They have been in the spotlight since they were precocious tots.

And Elle Fanning and her big sister Dakota have clearly always enjoyed a good dress-up session.

On Saturday, Elle shared an adorable video of herself and Dakota as little girls, getting their costumes ready for Halloween.

In the clip, Elle, now 21, can't be older than two or three, as she rifles through Dakota's toiletry bag while wearing cute clown makeup.

'That's my stuff!' the little Dakota — now 25 — warns. She is dressed in a furry pink top and cat ears. 

'What is this?' Elle asks curiously, holding up an eyebrow brush.

This flusters her sister, who exclaims, 'It’s for your eyebrows!' 

'And you’re not allowed to do it,' she adds bossily. 'Go get your wig back on!'

Elle proceeds to put on a big red clown wig.

'Getting ready for a girl’s night out with @dakotafanning #halloween #gogetyourwigbackon,' Elle Fanning captioned the sweet video.

She can also be heard giggling while presumably filming the clip on her phone.

Elle, who got her start as the younger version of her sister's character in the 2001 drama I Am Sam, is currently making the rounds with Angelina Jolie for their magical female-driven Disney sequel Maleficent: Mistress of Evil.

Dakota, who co-starred in this summer's Quentin Tarantino-directed Once Upon A Time In Hollywood, just wrapped The Angel of Darkness, a sequel miniseries to her prior series The Alienist, based on the award-winning novel.  

Both Fanning sisters have several other projects currently in development, including the lead in a Bell Jar adaptation for Dakota and the role of Russian Catherine II in a film called The Great for Elle, ensuring that these ladies will indeed continue to play dress-up professionally for a long time to come.
