Even though there are too many suits in the library alone to wear in a lifetime, Micheal comes to the conclusion that there are different suits in different rooms, but he doesn't know which room keeps which suits, if they would even have suits.

His choices of rooms are

Top floor:

A door with a cross.

The library.

The bedroom.

A... Bookcase?

Bottom floor:

Another bedroom.

A cellar door.

A door with a five pointed star on it.

A door with a fish on it.
