grace, fiona and rose arent in the art club and wich dress should i get?
Grace is in the art club in the morning, find Fiona at school in the afternoon, 1st Rose dialogue is in the library in morning or afternoon, 2nd she shows up in the library in the evening to call for potential sponsors (before that, you should talk to mom at work afternoon then buy the most expensive evening dress). Make sure all of these are done, else Jen will lose the competition.
Prior to the competition, Jen will need to have dinner with the potential sponsor. Make sure you have high charm skill to help Jen convince the sleazy scumbag, else some semi NTR scenes will play out.
This is how I played it anyway. I even convinced 5 (max) out of 6 judges to give their votes to Jen. The 6th judge is the main antagonist.
