Yeah song the hobby has nothing to do with when the event will start. That's good the more Sims you have designing fashion the greater your chances. I have already completed the Quest, but that was because I only had 2 Hair styles left to collect, but I would have about 3 days left if I didn't. Now my question for you is when you Start up the game do you see a promotion saying LONG HAIR EVENT IS BACK or are you just going off of information on this forum? If you have been seeing the promo then like I said just be patient and the event will start automatically. If you have not been seeing the promos then I would suggest just going back to playing the game normally until you do see them.
