Katie Price always wears matching underwear.
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.''
