This beautifully elaborate and jewel encrusted costume was designed by Anthony Powell for use in Indiana Jones and the Temple of Doom. It was used again several years later for The Secret Garden, where it is only seen briefly. It is difficult to tell from the front that it is the same costume, but the back allows for a better view of some of the detailing.
This particular costume is on tour as part of the Fashion in Film exhibit, and is used to point out to those that visit the exhibit, that costumes are often recycled for other productions, citing in the information this costume's use in both the above mentioned films. You can find tour dates for the exhibit here.
