Vani, playing her first full season on the LET, shot rounds of 73, 69, 77 and 67 for a total of two-over 286.
Vani, who started on the 10th, had a great first nine with birdies on 10th, 14th, 15th and 18th to be four-under at the turn. She dropped a shot on first, but a birdie on par-5 fourth made up for that. She ended with five pars and a card of 67.
Florentyna Parker came through a three-way play-off and won on the fourth play-off hole to claim her third LET title.
The last time she won was in 2014 at the Italian Ladies Open.
Florentyna, Anna Nordquist and Carlota Ciganda were all at 15-under in regulation and went into a play-off. Ciganda was the first to fall off and then Florentyna won on the fourth with a birdie.
Flortentyna, who was born in Germany, but spends a lot of time in England, carries both passports and had said she will decide on her nationality once the Brexit is done.
