How many clothes can villagers own?

[itangerine]

I gave some villagers about 4 pieces of clothing so far, while going through their wardrobes you can pretty much see 3 of those clothes so I thought they could just own 3 pieces but earlier I saw them wear their 4th piece around the island even though they were wearing their OG clothes moments ago.
has anyone figured out the limit of a villager wardrobe?
