The 23-year-old defender has joined on loan until the season’s end.
Brougham joined Manchester City’s Academy at the age of nine and made her way through the youth ranks before making the move to Everton in 2016.
After the switch to Everton, Brougham helped the Toffees win the FA WSL2 Spring Series title in 2017.
The move sees Brougham link up with former teammate, Claudia Walker, who led Everton’s attack during the FA WSL2 Spring Series.
Brougham will go straight into the squad for Blues’ match away to Reading on Sunday.
Emma Kelly is also eligible to play after her international clearance came through.
