When Charli is reminiscing about Paolo while the sisters are staying at Mr. Hammonds villa, there are black and white scenes while she and Paolo are at the Coliseum which doesn't happen until after the girls go back to work.
There is a sequence of "memories" the interns had during the summer that is shown, during that sequence there are shots shown that are of Charli's clothes which are not designed until after those "memories" are shown.
On Charli and Leila's first day back to work, Charli and Paolo have to make deliveries. The last thing they had to do was pick up some fabric. Paolo carries the fabric out and puts it on the seat of the Vespa. Charli is sitting on a wall and after talking her into some site seeing, Paolo picks her up and on the wall next to her is the fabric.
