polo

While 'polo' is commonly understood, 'chemise sport' (sport shirt) is a broader term that encompasses casual shirts like a polo shirt.

A polo shirt is considered casual wear. In French business culture, it's generally only acceptable in very relaxed, informal office environments, like a casual Friday, especially in industries that lean towards informality such as tech startups. It would be inappropriate for formal meetings, interviews, or gala events.

A polo shirt is typically made from 'maille piquée de coton' (pique knit cotton), which is a characteristic textured weave. The other options describe entirely different types of fabrics not commonly used for polo shirts.

Attending the opera in France typically calls for more formal attire. A polo shirt, being a casual item, would generally be considered inappropriate for such an event.

Yes, 'polo' is indeed a homonym in French, referring both to the sport and the type of shirt.

A polo shirt is typically characterized by short sleeves and a flat, folded collar, not a stand-up collar, and certainly not long sleeves in its traditional form.
