Kent were celebrating after they were crowned Twenty20 champions on Finals Day at Preston Nomads Cricket Club.
The team, led by Charlotte Edwards, beat Nottinghamshire by 10 runs in the semi-final before overcoming old rivals Sussex by eight-wickets in a one-sided final.
Having restricted Sussex to a meagre 107 for five from their 20 overs, Kent lost just two wickets as they successfully chased it down with 10 deliveries remaining.
Kent had beaten Nottinghamshire in the semi-finals earlier in the day.
Batting first Kent made 131 for four with Women's Ashes winner Tammy Beaumont shining with a well-made 47 at slightly better than a run a ball.
Nottinghamshire got close in their reply, finishing just eight runs adrift for the loss of seven wickets.
