Upper
This refers to the top part of your clothes, including your shoulders, chest, and arms. Think about where your shirt goes - that's the "upper" part.
Lower
This is the bottom part of your clothes, covering your legs and hips. It's where your pants, skirts, or shorts go.
Overall
This means the whole outfit, from top to bottom. It's like looking at all your clothes at once, not just the top or bottom.
Inner
Imagine turning your clothes inside out. The "inner" part is what touches your skin. It's the hidden side of your clothes that nobody usually sees.
Outer
This is the part of your clothes that everyone can see. It's the outside of your shirt or pants, the part that faces the world.
