The Mexican government accused designer, Carolina Herrera, of cultural appropriation in her latest range.
According to the designer's website, the Resort 2020 collection "takes on the playful and colourful mood of a Latin holiday".
But Mexico's culture secretary has written to the fashion house complaining about the use of patterns from indigenous communities.
A spokesman for Herrera, who was born in Venezuela, said the brand recognises Mexican artisans' work.
According to AP news agency, the spokesman added this particular collection was inspired "by the culture's rich colours and artisanal techniques".
