The lingerie and swimwear designer admitted she is fussy about her bras and knickers and hates to see people with a mismatched set.

She said: "I always wear matching underwear. In fact when I did that [model search] show - `Signed by Katie Price` - I couldn`t believe how many girls came in not wearing matching underwear. It put me off. Underwear says a lot about a girl.

"I can`t stand it when girls wear white bras that have turned that dirty grey colour but that`s just me."

Katie loves to promote her own range by wearing it and says when she can no longer model her designs she will give up.

She said: "If I can`t wear my own stuff then it`s time for me to give it up. It`s my product and I should be promoting it. I don`t agree with other people who have underwear out, who just wear a little dress and have models next to them wearing underwear. If you`ve got to promote your underwear you`ve got to wear it yourself. Otherwise what`s the point."
