HER stage clothes are bespoke by Chloe or by Burberry, and she has a particularly close relationship with the latter.
On her world tour she wore ten identical bespoke Burberry dresses in a Galaxy sequinned fabric in rotation.
Off-duty she wears a lot of plain black, although has a taste for eye-catching coats, such as the £5,000 Chloe shearling jacket she wore to have dinner with singer Bette Midler in London.
Her favourite designers include Valentino, Lanvin, Chloe, The Row, Armani, Alice Temperley, Valentino and Frame, and she likes 1960s and 1970s references. Her L.A.-based stylist Gaelle Paul works with her for everyday clothes as well as stage outfits.
