As much as I would say that Arabella and Billy ended up having Will Turner together(as it would be an interesting relationship between the characters)...I regret to say that I'm one of the majority who thinks they broke up, mostly because of learning of the death of Will's mother from Will talking to Jack in CotBP. Just me opinion of course.

As for Elizabeth's clothes, all I can say is that it's a intriguing coincidence.
