I believe at Hollywood Studios they have (or had) some of the costumes from the third movie. If I remember correctly it was Elizabeth's pirate king outfit and Sao Feng's costume. These costumes were placed among Vader's suit from the original Star Wars and the White Queen's battle outfit from the first Narnia movie and I feel like it shows how the series became more fantastical over time since the costumes didn't seem out of place among them. I don't know how historically accurate the costuming was, but it does feel like they started caring less about the period and more about coolness after a while.
