User blog comment:CrazyForLapidot/Peridot's New Crystal Gem Outfit Conversation. (My thoughts on the matter)/@comment-31587332-20160530165023

why would she keep her outfit with nothing but stars in place of diamonds? of course the crystal gem's stars can be replaced with stars: they're shapes! you could just as easily replace them with triangles or circles.

besides, now that peri is officially a crystal gem, regeneration would be a good step in finding herself. as we see in barn mates, she has changed drastically, and is proud of this change. freedom to express herself through her outfit would be welcome, considering that all 3 Rubies seen in The Answer all had the same outfit.
