* Holgado/a: This is a general term for loose or baggy and is probably the closest single-word equivalent. Use "holgado" for masculine nouns and "holgada" for feminine nouns.
* Amplio/a: This means ample or spacious and works well for clothing that is generously sized. Use "amplio" for masculine nouns and "amplia" for feminine nouns.
* Suelto/a: This means loose or unbound and can work, particularly if you're emphasizing the feeling of the garment not being tight. Use "suelto" for masculine nouns and "suelta" for feminine nouns.
* De talla grande: This translates to "large size" and is useful if the looseness is due to the clothing being a larger size than usual.
To choose the best option, consider what aspect of "loose-fitting" you want to emphasize. For example:
* "Loose-fitting jeans" could be translated as "vaqueros holgados" or "vaqueros amplios."
* "A loose-fitting dress" could be "un vestido holgado," "un vestido amplio," or "un vestido suelto."
Consider the specific garment and the degree of looseness when selecting the best word.
