Corrected entry: When Willie goes to save Shorty and Indy when they are trapped in the room with the spikes, she is wearing her silk pj's. However, when she is captured by the worshippers, she is wearing the outfit she wore at the dinner they had that night.

Correction: In the actual scene, only Indy and Short Round are captured, Willie is seen disappearing through a hole in the cave wall, at this point we can see that she is wearing the silk pyjamas. Even though the film does not actually show Willie being captured, it's obvious that she is also taken by the Thuggees, and while Indy and Short Round are being held captive in a cage, Willie is being prepared as a sacrifice, and she is in fact given a new dress, specifically for the sacrifice. Its not the same one as the dress used in the dinner, as you can see that there is not a separate skirt, the headdress is different, and much more.
