Even though you didn't underline anything, there is only one pronoun in this sentence - the word them.
The case of this pronoun is objective - it functions as an object in the sentence. It is really easy to determine this - all you have to do is ask the questions <em>whom </em>or <em>what. Whom did the designer dress in black and teal costumes? </em>And the answer is - <em>Them. </em>

Therefore, the correct answers are case: objective; function: direct object.
