A top is an item of clothing covering at least the chest, but usually covers most of the upper human body between the neck and the waistline. Women generally pair the tops with pants or skirts.

A blouse is a loose-fitting upper garment worn by workmen, peasants, artists, women, and children. It’s typically gathered at the waist or hips so that it hangs loosely over the wearer's body. Today, the word “blouse” mostly refers to a woman’s dress shirt.
