Material and cut/design.

Material is not just about quality, but rarity or uniqueness. For example, japanese denim can get very expensive in part because it's very low volume. For dress pants, it might be a particularly interesting fabric.

A lot of more expensive pants also have interesting designs or proportions that are very unique or hard to find elsewhere. There is a lot of cool stuff you can get for under $500 USD though, that is still pretty expensive.

Some examples around that price range:
