Bree's style went from a fun and colorful teen wardrobe in the Lab Rats TV series to a more stylish and sophisticated look in the spin-off Lab Rats: Elite Force. During the first and second seasons of Lab Rats, she wore a lot of brightly colorful clothes paired with equally brightly colorful combat boots. By the third and fourth seasons, her style was starting to change into something more stylish with cute sweaters, flowy tops, skinny jeans and cool ankle boots.
