The My World singer, who donned a pair of glasses at last month's VMAs, admitted that he cannot find the words to describe his style.
When asked to explain his fashion sense, Bieber told ET Online: "I don't really know, I can't really describe it. I just think it looks good, that's all."
Of launching his own clothing range, Bieber said: "You know, maybe down the line, I'm not opposed to anything. But right now, I'm focusing on this next album."
Meanwhile, the 17-year-old also declared his admiration for rapper Kanye West's fashion knowledge, adding: "I think Kanye West has great style."
Bieber recently announced plans for a Christmas album.
