Have you ever played
Game of Whores? It's a 2D game based off of the Game of Thrones universe, as you may have guessed. It has a wardrobe system very similar to the two games you showed pics of. The outfits have little effect on the gameplay in terms of stats, and they are bought in a shop. Also, I'm sure you know, but most Trainer games (especially the Akabur ones), like
Witch Trainer and
Princess Trainer have wardrobes. IMO the one that has the best customization out of the Akabur ones I've played is Witch Trainer, more specifically,
Witch Trainer Silver, since that's the version i've played. But some other non-Akabur ones are
Paprika Trainer and
Jikage Rising(Which technically doesn't have "trainer" in the name, but is a trainer game in spirit).
Third Crisis has a wardrobe system, but I haven't played much of it. The gameplay seemed somewhat unfocused/undriven or something, but it could be that I'm missing something. And last, but certainly not least is
Lab Rats. I've only played
Lab Rats 2, but I assume 1 is similar. It's a 3d game, but it has the most in-depth outfit customization I've ever seen. There are a lot of options for what clothes can be worn, and you can freely customize the color of
all of the clothes, even being able to change the colors as well. The main gameplay is a tycoon type thing where you manage a company which makes various drugs, some of which you use to control and corrupt girls, eventually making them submit to you.
I hope this helps you, and any other people who read this thread!
