Now when you see her later on in the film when she is sitting by the dining room table with Dennis Hopper eating when she gets up she is wearing purple lacy underwear 01:02:26. Later on when she is fighting the man with glasses from under the bed, when you see him pulling her legs in order to get her out from under the bed you see her wearing black knickers 01:19:32 or you can get a better shot at 01:19:33.
