Well, of course, Kanye West isn't going to be taken seriously in the fashion industry. It is sad though because it is clearly something he is very passionate it about, but I strongly believe that the fact that he is a black man (do not mention the race card to me, don't even try it) and his outspokenness probably has hurt him a lot.
However, he is doing what he loves and I don't understand why people try to tear him down for that reason. Say you don't like his clothes, but don't say "Kanye should know his place" or "Kanye's should just be a rapper."
Stop trying to box people in and let them do what they want to do. If it isn't illegal and isn't hurting you mentally or physically, let these people be and allow them to chase their dreams..
