i think that Ford was far more respectful to ysl´s legacy, than ysl himself to him, he always interpreted his work in one way or another and do not forget that ysl´s clothes from the past weren´t necessarily for shrinking violets, whenever i read a comment on how ford´s collection´s for Saint Laurent were to sl*tty i cannot kept on thinking about Saint Laurent being the first ever designer to include sex and scandal on his runways decades ago.
sorry but when i hear people refering to YSL and his legacy like the way you did (comparing it to ford´s work as it not representing it "respectfully" enaugh) at least i sense it as being a very uptight, classic, almost boring desing house, and it was far more than that, including heavy doses of sex and hedonism, Pilati has turned it into one of the chicest house around this days, but we have to admit most of his collections have been much less confrontational than fords (except his second), which isn´t necessarily a bad thing, but i guess if we compare in terms of personality, ford is more similar to Saint Laurent than Stefano and since the designer is the soul of the collection is hard to believe that ford was wrong for YSL, but since he had to go, thankfully we have Stefano doing wonders there too.
