I mean they could just have a "browse different stalls for clothes" so that it thematically is you just going through a bunch of the market stalls looking for clothes. Then it presents one list to buy from. If need be, have this inventory reset every day or every other day - but id prefer, for fun gameplay, to make it just have all options
Well, I can see how a Mall wouldn't really fit the setting, but then, why do I hand out flyers to get people go shopping at the market instead of the mall?
I think there should be a permanent clothes shop where you can get regular stuff. While I can accept having to scour the market for some fancy dresses, I'd hate to do the same just to replace some lost panties or buy a different skirt or blouse.
What I really miss is a preview option so I can decide if I like the look of an outfit before I spend the money and get home. And some info for which clothing category a garment is usable. E.g. I like this T-shirt, but can I wear it as a sports top?
