Can you remove underwear while wearing pants topologically?

The question is asking why it's topologically impossible to remove underwear while keeping pants on. Topology is a branch of mathematics that studies the properties of shapes that are preserved under continuous deformations. In this case, we're dealing with the topology of clothing. The key insight is that the underwear is 'nested' inside the pants, and removing it requires creating a temporary hole or deforming the pants in a way that's not continuous.
