Been of a fan of the iDOLM@STER ever since I was a teenager through the middle 2010's! Well, I actually stumbled upon the ONE FOR ALL/OFA game somewhere around early April of 2014 of the year if I remember correctly.
And when it comes to the characters' own costumes that will appear, they're recolored by me.
First up, here's Ganaha Hibiki with this recolored Starry costume!
Plus, there's a cameo of that Macaron Cat Animal Sweet from Kira⭐Kira Precure à la Mode to hold the one end of that drawing since that bottom right corner was flipped and crumpled there.
Next up, we got Kisaragi Chihaya wearing a recolored Luxury costume of her own!
Lastly, we got Mizutani Eri AKA "Ellie" wearing a recolored Luxury costume! And I'll take to imagine it's the "Evergreen Leaves" pattern since I would love to see that on her if anyone can mod that in THE iDOLM@STER 2 video game somehow.
Oh, did I mention that all of these were traced off of YouTube videos? Yeah, I still watch iDOLM@STER stuff on YouTube to this very freakin' day! They were also originally drawn back in the middle 2010's.
