Lanvin is an old French house that has been under revival. The women's line is highly priced, adn regarded designed by Alber Elbaz former onetime designer of Yves Saint Laurent Rive Gauche. However I believe that certain aspects of the men's lines are still under license similar to Givenchy Homme.
Prices for women or men are in the same range : RTW suit = around 2 000 euros Shirts = around 110/120 euros 7 fold tie = 170 euros tie = 90 euros A friend of mine has 40 % off all year long and 80% off one day before sales (sales for employee and friends). I guess I will spend a lot of money during summer sales.
