Ashley Jensen - you could go as her in Ugly Betty - a bit fashiony?
Dawn Steele - she's in Wild At heart now, you could go safari ish? NB I don't watch it, she may not actually wear safari style in show!
Kirsty Hume, Stella Tennant (models), and just wear lovely things?
A character from a Jack Vettriano painting ? The Red Dress one??
