And the designer thinks Mossy is the most stylish person to tread the planet, too
'Kate bought a pair of those boots and then everybody wanted them,' Dame Viv says in a new video for Topshop.
'She loves fashion, she understands clothes. She knows how to work clothes. I think Kate is the most stylish person that treads the planet,' the designer continued.
Ms Westwood who turned 72 last week, also revealed what it's like to be a good friend of the supermodel. 'She's got a big aura that she draws you into. Every time she speaks to me I feel like we're in a conspiracy. She's so intimate that you want to to know what we're going to be doing together.'
Meanwhile, Vivienne Westwood's boyfriend, Andreas Kronthaler, thinks Kate is 'so sexy.'
'But I'm more beautiful,' Vivienne said. 'And that's that.'
