After Julia Roberts has bought her new clothes, she is walking down the street to the sound of Pretty Woman. A black purse is clutched under her arm. When she enters the shop where the clerks had refused to wait on her the day before, there is no purse under either arm!
She's holding like 5 bags/boxes, so maybe she stuffed her purse into one of the bags to make less for her hands to carry. I know I do that when I go shopping at the mall.
