noun. vest [noun] a kind of sleeveless shirt worn under a shirt, blouse etc. (Translation of camiseta from the PASSWORD Portuguese–English Dictionary © 2014 K Dictionaries Ltd)

If you're referring to a button up shirt with a collar, then camisa is the right word. It can be a camisa con mangas cortas (short sleeve shirt) or con mangas largas (long sleeve shirt). The only other word I had ever heard for shirt was camiseta, which all my books defined as a t-shirt.
