The runway legend took aim at the topless model-turned-reality TV star after watching her U.K. series, What Katie Did Next.
Moss, who has her own perfume line, was shocked to see Price splashing on scent for over ten minutes during one episode - and is adamant the star must reek.
She says, "Don't wear too much so that it leaves a trail behind you. Have you seen Katie Price's programme? She wears too much.
"I've never actually smelt it, but she sprays herself for about ten minutes. I'm like, 'Oh my God, what is she doing?' I don't think that's a good look. It should be subtle enough that you can smell it, but not so that it's overdone."
