Sandy Dumont is paid by companies to improve how their staff look. The idea is that after a session with the Virginia-based corporate image consultant, they will look nicer and so be better at their jobs. Clients have included companies as diverse as ITT, American Express Financial Services, Rolex and Honeywell.

"I do a lot of financial institutions, business schools, anything that's very competitive," she says. Americans "recognise that this is another tool for getting ahead. They are willing to pay and do whatever they need to get on the fast track."

A work-related makeover means looking at things like clothes and shoes, make-up, glasses, hair and teeth.

Some companies pay for the sessions, especially group ones, but some individuals buy their own one-on-one consultations.
