She's a dedicated follower of fashion, walking the red carpet in the most coveted designer gowns. But on Saturday Millie Bobby Brown fell victim to the perils of fashion, kicking off her heels for a more comfortable exit from a fan meet and greet event at an Ulta Beauty outlet in the U.S.

The Stranger Things star, 15, showed off a cute lilac jumpsuit with an open collar and waist sash as she emerged barefoot from the store, heels in hand. Looking every inch the burgeoning film star, Millie rocked her beautiful outfit which was complemented by her golden-tipped brunette tresses. 

The star's outfit was from New Zealand-based sustainable fashion brand Maggie Marilyn.  Millie's appearance comes after the star put on a stylish display last month when she launched her Florence by Mills beauty range at a London Boots store.

She earlier announced plans for the new range in an Instagram video.She explained: 'Every young person deserves to have a good start with their skin.' I wanted it to be vegan, clean, cruelty-free, that would be easy to get and fun to use, and still youthful, but you know, playing that sophisticated teenager as well.'

Millie added: 'What I want my beauty brand to represent is individuality, and embrace who you are. All I know is that I want you to feel yourself.'In the caption to the Instagram promotion, she revealed that she had spent two years developing the line for her age group.
