Identical twins' photo edited to create distinguishing factors

Photo editing request (example): "Here is a photograph of my identical twin daughters Victoria and Valerie. Clones, right! They are keen to act in a play that has twin sisters in the storyline. They've been asked for photos before the audition, and I think this 'exact copies' photo is taking things too far and may not necessarily impress the selectors. Would you do a few things to make them look a little distinct from each other. Give one of them a maroonish top. May be throw in a tattoo and some accessories... or anything else you think appropriate. I want the judges to be able to differentiate between them — 'the one with the tattoo' / 'the one in the maroon top' etc."
