Does boyfriend want to show me off or what is this about?

We’re going to a family function of his as a couple for the first time. He asked me do I have a nice dress, and a few days later he mentioned the dress again out of the blue and asked what does it look like. We’re going to meet his extended family as well as some other acquaintances of his. Does he want to show me off to people or why this interest in the dress?
