polo

Short answer

In Lima, "polo" means a t-shirt. The register is neutro — fine among friends, out of place in a job interview or anything written to an institution. The standard Spanish equivalent is "camiseta". In use: Compré dos polos en Gamarra.

Not the sport, not the collared shirt English speakers mean by polo shirt — just a plain t-shirt.
