Personally, I think Pilati needs to start putting his heart and soul into YSL. He needs to recreate it and completely make it his own. He needs to turn it into something he will be remembered for (in the positive sense). He needs to stop trying to impress the critics just because he feels that for so long he hasn't, and most importantly, he needs to completely disregard the fact that Saint Laurent is still around. He was appointed head designers for a reason, he needs to take advantage of this position and make a difference for the better at YSL.
His lack of self-confidence saddens me as I feel that he is a talented man. He's been fed (for too long) that he has these limits and etc etc. He only has limits if he gives himself these limits. It is a designers JOB to disregard a critics opinion if he truly feels that what he is doing for his line is the RIGHT way to go. This is what YSL himself did while at Dior, the outcome wasn’t great initially with him being fired but it worked out in the end and from it came a line I cannot see the fashion world without – Yves Saint Laurent. His designs, initially deemed shocking/rebellious and the reason he was fired were later copied by Mark Bohen for Dior after they had caught on.
You need to stay true to your beliefs, if you cannot do this, designing isn’t the job for you. Instead of going into the creation of a line with the mind-set of "Okay, what can I do to IMPRESS these god forsaken critics/editors?” he needs to go into it thinking "Alright, how can I recreate YSL THIS season? How can I translate my hearts belief of what YSL is to me, into something in the physical sense? How can I put it all on paper?". With this mind-set should come an unforgettable line. Fashion isn't about perfection. If it was, I would have lost interest a long time ago.
