She stars as Belle in the live-action remake of Beauty and the Beast, and Emma Watson has been hard at work on the publicity trail to help promote the movie.

The 26-year-old actress was seen arriving at the Jimmy Kimmel Live! studios in LA on Monday, dressed in a grey pantsuit.

A hint of her lacy black bra could be seen underneath her blazer, and she accessorized her androgynous look with strappy black heels and a slick of red lipstick, her hair pulled back.

The Harry Potter star has committed herself to wearing only ethical clothing as she promotes her latest film, and has even started an Instagram account called The Press Tour, where she has been detailing each of her looks.

Emma put fashion’s elite through their paces while sourcing outfits for the Beauty and the Beast press tour, reportedly sending a PowerPoint presentation to designers, asking them how their garments are produced, what their impact is on the environment, and the moral reason behind why she should wear their clothes.

And while the English beauty was happy to sign autographs and wave at fans as she made her way into the Jimmy Kimmel Live! studios, it’s unlikely she posed for photos.

In an interview with Vanity Fair this month, she confessed she refuses to take selfies with fans anymore.

‘For me, it’s the difference between being able to have a life and not. If someone takes a photograph of me and posts it, within two seconds they’ve created a marker of exactly where I am within 10 meters,’ she told the publication. ‘They can see what I’m wearing and who I’m with. I just can’t give that tracking data.’

Although she’s now selective about her interactions, Emma says she’s still happy to give people a piece of her time.

‘I’ll say, “I will sit here and answer every single Harry Potter fandom question you have but I just can’t do a picture” – and much of the time people don’t bother,’ she said. ‘I have to carefully pick and choose my moment to interact. When am I a celebrity sighting versus when am I going to make someone’s freakin’ week? Children I don’t say no to, for example.’
