Lea Thompson still has her 'Back to the Future' prom dress

Los Angeles: "Back to the Future" star Lea Thompson has kept hold of her perfect prom dress from the movie.

The actress revealed that she still has her 1950s pastel pink dress from the Enchantment Under the Sea Dance, reported People magazine.

"I can't get in it any more, though. It was so tight! It was tight at the time, but now it's really, really tight.

"It was beautifully made, and made to order for me. It's got a low-drop waist, and the way it was cut was just so beautiful. And it's still in great shape. I've still got the shoes. The shoes are even hard to get on now - my big ol' feet from having babies," Thompson said.

The actress was 24 when she filmed the first "Back to the Future" movie, and she admitted that the form-fitting dress made life a little difficult.
