LORELAI: What’s with the muumuu? [gestures to Rory’s baggy sweater.]
LORELAI: No, I’m just saying, you couldn’t find one made of metal in case anyone has X-ray eyes?
A possible allusion to the 1963 sci-fi horror film The Man with the X-Ray Eyes, directed by Roger Corman and with Ray Milland in the title role. Made on a shoestring budget, it was nonetheless successful and well-received.
The teenage Rory is apparently self-conscious about her developing figure, and Lorelai teases her about it. Despite the lack of response from Rory, Lorelai’s criticism seems to have been taken on board: although Rory always dressed modestly, she never again wore anything this thick, baggy and shapeless to hide her body.
