I'm not talking about the festival plaza's dyed clothes. I'm referring to the other clothes that you can obtain in shops throughout the four islands. These items are largely exclusive to one game or another, with a few items being available in both.

@Garblon Yes, and I'm not talking about festival plaza's dyed clothes either.

You can get them, by talking to someone who wear the clothes in festival plaza.

For example, you play Sun, and  you want to get Blue colored clothes you can only get from clothing shops in Moon, here's step-by-step:

1. You can ask one of your VIP Friends to wear that clothes you don't have in Sun.
2. When you've get their newest Festival Plaza updates, talk to them and choose "Your outfit looks great" options
3. You can bought their clothes using FC.

Note:
1. You get this option when you've reached lv 10 in Festival Plaza. (Rank Up Bonuses here: http://www.serebii.net/sunmoon/festivalplaza.shtml)
2. You can also ask this to your guest.
3. You can't buy dyed clothes.
4. You can only buy them one by one.
5. It's expensive, like @DeKuSkrub said.

So, yeah, you can get every piece of clothes, including version exclusives, legitimately. Even though it needs load of time, patience, and FC. PKHex is here to help you cut all of that.

Even with that in mind, there are still pieces of clothing that are exclusive to each game.

@Garblon Nope, you can get all of em from Festival Plaza.

Or can you list what clothes are exclusives to each game? If you're thinking about Blue colors which are exclusives to Moon, you can get all of those in Sun, through the festival plaza.
