Over the past several decades, there has been a considerable shift in the form of masquerade costumes worn during Trinidad Carnival. With the growing popularity of Carnival, there are increasing concerns about whether the modern style of costume will lead to the disappearance of Carnival s traditional meanings. This study employs an ethnographic methodology to understand dress at Carnival in the context of a 21st century global society. Data collection took place in Trinidad during the Carnival season and employed the methods of participant observation, depth interviews, and photographic documentation. Data were analyzed for emergent themes, and an interpretation of the significance of changes in masquerade costume for understanding Carnival was developed. Further research on the role of the dressed body at Trinidad Carnival is needed to fully examine the power of dress to define Carnival and shed more light on its importance.
