as a hollow object.
A normal shirt already has openings.
The neck is an opening into the inside.
The sleeves are openings into the inside.
The waist is another opening.
If you cut a new opening into the front of the shirt, you create another route between the outside and inside.
If the cut also passes through the back, you may create another opening on the opposite surface.
This produces a much more complicated topology than the simple “four holes” answer suggests.
