sweatshirt and sweater 有甚麼分別

I worked in the garment sector and this is my understanding:

Sweatshirt: refer to those causal and sporty clothings.

If you go by the book the two words mean the same and are interchangeable:

http://en.wikipedia.org/wiki/Sweatshirt
A sweater (also called sweatshirt, pullover, jumper, and jersey) is a relatively heavy garment intended to cover the torso and arms of the human body (though, in some cases, sweaters are made for dogs and occasionally other animals) and typically to be worn over a shirt, blouse, T-shirt or other top. Sweaters tend to be, and in earlier times always were, made from wool (typically of sheep, though possibly of alpaca or other type); however, they can be made of cotton, synthetic fibres, or some combination thereof.
