I couldn't find any sites that showed what different Personal Quarters Themes looked like (outside of the tiny in-game images) so I threw together some short videos over the week to help showcase them!
Note, I started on PC, so I haven't been able to complete some of the older sets yet, but I hope that these videos will help you if you're trying to pick a theme or just wanted to see what they looked like!

Fancy Theme: https://youtu.be/Xdb9DAJW6k8
Resort Theme: https://youtu.be/MPAc51XFENo
I also have other videos up already.
I used large rooms when showing the themes, the small will vary slightly for some. If anyone has any suggestions for improvement or showcase requests, I'm open to hearing it! I just do this as a fun little side thing, so I haven't gone out of my way to make the rooms look great thus far XD I just wanted to show the themes, furniture, and PSO2NA names so you could find them in player shops!
