Continuity mistake: When Lara Jean and Peter are creating the contract, the writing for the "Ski Trip" changes between when Peter writes it and when they sign the contract.
Continuity mistake: Peter is in Lara Jean's kitchen, wearing a jacket. Her dad comes home, he and Peter shake hands, and in one brief shot Peter is not wearing a jacket but a plain short sleeve top. Angle changes again and the jacket is back. (00:39:00 - 00:40:15)
Continuity mistake: When Peter is talking to Lara Jean about the letter when they are in the diner, the straw in Lara Jean's glass changes position between shots, and changes from white to clear. The cherries also disappear or move.
Continuity mistake: Lara Jean is baking cupcakes at sometime in the day (we know this because its light outside). Peter then comes to pick her up for a party. Once they are at the party, Peter makes LJ change her lock screen to him and when she asks what his is, he shows her, but we see on his screen that it is now 12:18am. No way it took them 6 hours to get to the party.
Continuity mistake: When Lara Jean nearly hits Peter with her car, she first puts her seatbelt under her arm then when Peter comes to the window it's on normally.
Continuity mistake: When Peter picks LJ and Kitty up for school when they start fake dating she is wearing pink but when they get to school she is wearing a yellow striped jersey.
Suggested correction: That's because it's not the same day.
Continuity mistake: In the scene with Chris and Dr Covey in the kitchen when Lara Jean comes in she wearing a scarf and takes it off and puts it down to sit, in the next shot she's sitting on the couch and takes it off again.
Continuity mistake: On the ski trip Lara Jean goes in the hot tub with her nightgown on, but when she gets back to her room and lays down it's completely dry. (01:07:48 - 01:09:13)
