regards! the game does not let me sell or melt objects since they are in "use" in one of the 5 sets of the character, how can I eliminate them? so that it leaves me free space for new things?
It is what the message says: make sure the item you want to sell/melt isn’t equipped in one of your wardrobe slots (a, b, c, etc.).
Simply, remove them from your item sets and melt or sell them
