Millie Bobby Brown's foray into the fashion world all started with her success playing Eleven on Netflix series "Stranger Things." Brown first proved she's got serious acting skills, then plenty of red carpet appearances followed. She developed a relationship with major brands like Calvin Klein, starring in a 2017 campaign at age 12. The star, who recently announced her engagement to Jake Bongiovi, also signed with IMG models that same year. Since then, Brown has launched her own beauty line, Florence by Mills; collaborated with Converse; and attended many a Coach runway show to sit front row during Fashion Week.

While a lot of Brown's off-duty looks veer on the side of ultra casual, she works with stylist Michelle Kelly to construct her wardrobe for appearances. For her red carpet looks, Brown experiments with flirty hemlines, colorful embroideries, and avant-garde silhouettes that pack a punch, while still remaining youthful.

Her latest share with fans is an Instagram post featuring a knitwear set. In the photo, Brown poses near a window displaying the Chicago skyline wearing a matching short-sleeved top and miniskirt. She accessorized with black knee-high boots, a brown shoulder bag, and small gold hoop earrings.

Ahead, see more of Brown's latest outfits — and scroll back in time for her full style evolution.
