Question

Fix the pronoun error (if one exists).

Each of the costumes
Each of the costumes
All of the costumes
in Hagrid's closet had sequins or feathers all over them.

Answer 1

The pronoun error in the sentence is with the use of "them" when referring to "each," which is singular. Here's the corrected version:

"Each of the costumes in Hagrid's closet had sequins or feathers all over it."

Alternatively, if referring to "all," you could say:

"All of the costumes in Hagrid's closet had sequins or feathers all over them."
