What is the difference between ホワイトシャツ・ワイシャツ and 背広?


How do we decide whether to call a shirt a ワイシャツ or 背広 ? What's the difference
in nuance between the two terms?

Side question: [EDICT](http://www.csse.monash.edu.au/~jwb/cgi-
bin/wwwjdic.cgi?1MUE%E3%83%9B%E3%83%AF%E3%82%A4%E3%83%88%E3%82%B7%E3%83%A3%E3%83%84)
claims that a ホワイトシャツ is a white business shirt but even if it's a gray or
black (or what-have-you) colored business shirt, we can still call it a
ホワイトシャツ or ワイシャツ right?




I think you're confused here. 背広 is a suit, not a shirt. As to the second
question, ワイシャツ is the generic name for a dress shirt, button-down shirt,
oxford shirt, etc. Color doesn't enter into it. Also, ホワイトシャツ is archaic now.
