Nurses have voted in favour of having a colour-coded uniform across all NHS trusts to stop patients and staff becoming confused.
Health workers at the annual Royal College of Nursing (RCN) conference in Harrogate, North Yorkshire, said current uniforms where hospital staff wear similar colours for different roles lead to confusion.
Damian Ronksley, 31, a student nurse from Sheffield, proposed the motion saying nurses in some areas wear the same colour as cleaners in other sites.
He said: "All trusts tend to have different uniforms. It's confusing for staff so it must be confusing for patients."
Instead, the workers at the conference agreed that uniforms should be colour-coded according to rank and standardised across the NHS where appropriate.
This could mean all nurses of a particular rank wear one colour or shade, while ward sisters wear a different one.
Mr Ronksley has called for a scrub-style tunic top and trousers, which are comfortable to wear and easy to wash.
A similar scheme has already been approved by NHS Scotland, with staff required to wear a standardised uniform by 2012.
