I only looked in the more populated locations, so I haven't scoured the wild parts of the Wishing Woods. Though some of them I apparently walked past at some points and just didn't see before I took a second look in that location...
Arubida appears to be an event exclusive character, since he also appeared in the Shooting Star Season quests, so he does not appear in the Wishing Woods.
Alibo also does not appear as they were the minigame facilitator.
I am unsure if some of them appear or have different dialogue if you haven't done Revelry Season quests (I'll check when I eventually get my alt here).
Image heavy so under a cut ⬇️
Moosda - Eastern platform of Residential Area
Morda - Eastern platform of Residential Area, next to Moosda
Aneda - Wish Inspection Center, northern platform
Valenbo - west of the Research Institute
Philbo - Residential Area, back of the Quick-Flight Fire Station
Kubibo - Platform south of the Wish Celebration Center
Domilada - Platform south of the Wish Celebration Center, next to Kubibo
Don't know if Domilada's dialogue will be different if you didn't do the Revelry Season sidequest about him.
Flofubo - Northwestern part of Timis's Beauty Lab, south of the horizontal fallen tree
Palida and Pamoda have also been returned to their original locations on the road between the Wishcraft Lab and Timis's Beauty Lab (they weren't here during Revelry Season)
Incidentally, there's still a sort of mini mystery in the Revelry Season that I'm not sure is solvable yet or ever meant to be (which isn't a bad thing but I just like Knowing Things)
It seems that while Crimson Rhapsody is Valenbo's own design, the Art of Tailoring itself is designed by a different Faewish Sprite. Valenbo says it was designed by her idol...an unknown bo sprite who was a previous Party King at some point!
Interestingly I feel like Valenbo's descriptions of this Party King are a kind of veiled reference to Aderinna. What we know of this Party King is that she earned the title using her "scissor dance" (which Valenbo calls "so cool!") and had a "rebellious" style. Note that Art of Tailoring is a Sweet outfit though.
I imagine from an in-universe standpoint the Art of Tailoring appearing on Nikki is basically the Mask calling up an old memory of the design
(Also, confirmation that, at least in English, Party King is a gender neutral title)
i like to headcanon that Siyabo was the Party King that Valenbo idolizes, which by extension makes her the designer of Art of Tailoring in my fanon I guess
