Did Anyone Else Notice This?

If you dress your MC in the Dreamer's Nightwear outfit, side characters in the game make comments about you being in pajamas. Ex: I just walked by Sebastian and he went, "Are you wearing pajamas?" And when I was in Professor Hecat's classroom, she said, "Where are your school robes?" I thought it was a funny detail, but I haven't noticed character commentary on any other items of clothing when you wear them.
