Yup! Same goes for Paddy too, and they’d also have totally different outfits, so I decided not to include them for now (especially because I’m not really that good with character design). 
I was originally going to draw them in their party/sleepover outfits, but I thought the fieldtrip outfits make more sense to be on the character page.
If you liked the new drawings, everyone will have a different outfit for each story world, so you have those to look forward to as well!
Edit: Hello! I just uploaded a tiny update!
v2.1.3.61 Update
- You can now choose what uniform MC and their twin wears.
- Increased relationship with Maggie if MC has told everyone about their thoughts on their gender.
- The ripped pages on Maggie’s diary entry now only appear if you replaced your locket picture.
- Added a picture of the F6E wearing their fieldtrip outfits when the demo ends.
- Roselyna is now more huggable than ever!
Anyway, I’ve thought about it some more, and now I’m planning to have Aunt Julie and Uncle Robert (and maybe the pet too?) to appear one last time in Chapter 7 during the school invasion. I just can’t have Chapter 3 (or Chapter 5 in the investigation branch) be their last appearance for a long while, you know?
