Answer: The two object pronouns are "te" and "las."
Explanation: Just to elaborate a little on the answer, it can be added that the first sentence can be translated as "They show you the blouses" (subject + verb + indirect object + direct object). Alternatively, you could say "They show them to you," and you would say that by using the personal pronoun "te" in its dative case (to you) and the personal pronoun "las" in its accusative case (them).
