I found these sprites and portraits from a seasonal clothing mod that was never made.

I was browsing old Stardew Valley forums when I found these sprites and portraits,Apparently, they wanted to make a seasonal outfits mod (and judging by the dates, the first mod of its kind) but it was never completed.
I gathered some images that interested me (there were only a few previews of Jas)

Someone could complete it.

The usual courteous thing to do is check for whether they gave anyone else permission to play with it. And of course credit the artist, even if they did.
