Schools should not require branded uniforms, a council has said.
Portsmouth City Council said parents with children in state schools spend an average of £337 per year on school uniforms.
Most require pupils to buy branded items "which are often significantly more expensive than unbranded alternatives", the authority said.
Instead, it suggested parents should be allowed to iron or stitch logos onto unbranded items.
A council motion said it would write to schools requesting they stop the use of mandatory branded uniforms where unbranded items can be bought at more affordable prices.
The authority agreed that, during a cost of living crisis, "there can be no justification for school uniform policies which require families to purchase branded items which are significantly more expensive than unbranded items".
