Meaning of Garments is "A garment is a piece of clothing". The area of New York City where clothes are manufactured is known as the Garment District.
Derived from the French word for "equipment," garment is a somewhat generic term you can use when the specific kind of clothing you're describing is not the point. A dress, for example, is a dress, and pants are pants. They are not the same thing, unless you refer to them both asgarments, in which case they are the same thing.
