Most of the costumes as well as other props were sold not long after the hysteria over the movie started. But there may original buyers willing to sell - I have noticed from time to time Titanic movie costumes up for auction on eBay. They would be quite pricey though. Others are w/ 20th Century Fox I imagine. Still others were exhibited (& some donated) to the Fashion Institute of Design & Merchandising in L.A. The "Sense and Sensibility" website of Jennie Chancey's has info/pics on the Titanic costumes & other links are provided too.
