Kanye West thinks making a bad fashion purchase is like getting a ''prostitute pregnant''.

The outspoken rapper has branded both an ''expensive mistake'' and believes bad buys come from a lack of knowledge.

He said: ''When I was young, I was really scared to walk into luxury stores, too. It's very non-inviting and it's very expensive.

''Like, f**k if you're not knowledgeable you can make a very expensive mistake - it's bordering on getting a prostitute pregnant or something like that.''

Meanwhile, the 'Stronger' hitmaker - who recently unveiled his own Yeezy Boost x Adidas Originals collection - is glad his level of fame can be used as a ''tool'' to help him go places in the fashion world.

When asked if he ever gets tired of his celebrity status, he told France's Clique TV: ''No, not anymore. I'm very happy to be famous. It's a tool that you can use to message as you want to take the power into your own hands.

''As far as my narrative, they can write whatever they want to write... I don't care about what anyone in fashion has to say about what I want to do. I'm here in fashion to learn sensibility... I want to create something comparable to what Walt Disney did and then mix it with what Henry Ford did and mix it with what Howard Hughes did.''
