Marc Jacobs:
The fact that he can come off as a fraud. Often times, just because his name is attached to them, very banal, boring, or truly hideous pieces become instantly fashionable. His 'cool' factor is enormous, but the designer in him, it seems, is a far weaker man than his marketing genius. His last LV show proved my point.
Also, I do not appreciate the 'I do ugly accessories and shoes, because I am too cool for school' mentality. Most of his bags are hideous to no end, and all the nice things about them are either stolen from Prada or Chanel. And shoes are too gimmick-y. One in a while, his playfulness leads him to true genius, and he is a huge talent, one must admit. But he is sloppy, and often lazy, just because he knows whatever he does will ultimately sell like crazy. He does very little to push himself, or challenge his vision and eye.
Theykens:
The fact that he cannot design anything else other than his fabulous gowns. He is a completely useless artistic director. He must surround himself with people capable of creating a range of products and garments, under his direction. He doesn't fit into today's description of what a luxury brand and fashion designer is supposed to be, even though he single-handedly designed some of the most beautiful gown any of us will ever see.
McQueen:
The fact that he still could not manage to create a design universe, or a signature look. His stubbornness and caprice do cost him a lot, and it is sad to see that this is one designer who could never take the next step to both creative and commercial greatness: the level of greatness that has been begging him to be achieved. Maybe now, it is too late. I do not think his brand will last after his death or retirement, since it is always a hit or miss situation with him.
Also, the fact that his highs are too high and his lows are abysmal. Most of his clothes are marvels of construction, with no usefulness or singular merit. It will be horrible if people remember him with just a few spectacular gowns and a skull scarf, after his death, like some ancient relic from the pages of once-upon-a-time fashion history.
Giorgio Armani:
The insistence on being unbearably demode and boring. The fact that even though he is the wealthiest designer in the world with limitless resources, he never felt the need to train any other young talent to replace himself one day. The fact that he still doesn't know what to do with color. And the fact that he tries so hard to cheapen his brand by attaching his name to the likes of Beyonce and Josh Hartnett.
Donatella Versace:
The fact that under her direction, Versace mensline became an editorial and commercial joke. A line once defined, and defied everything that was in style, now is just a grey suit with a lavender shirt. Also, the fact that Versace shoes and accessories are still bleeding and could not become anything worthy to speak of. The company still could not succeed in investing in accessories. Even Chloe is far more inventive and successful than Versace. Her seasonal and fragrance ad campaigns are also usually tacky beyond belief.
Miuccia Prada:
The lack of a jewelry line. She must bring back cool costume jewelry back to the forefront of fashion. She is the only person who can do it. I also hate her use of zebra wood-veneer in the SoHo store. It was a crime against the environment and the rainforest. And now, it looks old and worn-out.
