Originally an undergarment worn exclusively by men, it has become, in American English, a catch-all term for a broad variety of upper-body garments and undergarments. In British English, a shirt is more specifically a garment with a collar, sleeves with cuffs, and a full vertical opening with buttons or snaps. A shirt can also be worn with a necktie under the shirt collar.
But let history be history and talk a little bit more about the nowadays shirts for women. Even if this item was made for men, throughout time women enjoyed of this “invention”. I found some shirts that you can wear almost anywhere.
