Plot hole: When Carrie calls the girls from Aleksandr's couch, she is wearing one outfit. In voice-over, she says she stayed at his apartment for 4 days. But then when she finally arrives home, she is wearing a completely different outfit. How would she have so many clothes to wear, when she didn't expect to be away from home for 4 days? She wasn't carrying any luggage or other clothing with her when she came home, either.
