I'm disappointed that Rey is in all white. That seems to be too obviously playing to the "good guys wear white"/"bad guys wear black" trope and not doing anything to help the Mary Sue accusations. I really liked that Luke wore black throughout RotJ because it subverted that trope, gave him an edge and raised the possibility that there was a "dark side" to him so that we might wonder if he might turn into his father, who also wore black. Rey wearing white has no mystery to it. It suggests that she's a wholly pure good girl who'll always do the right thing and defeat the bad guy in black in the end. We suspect that, anyways, but it would've been far more interesting and raised a little doubt in viewers' minds to radically change her look and put her in black, as was done with Luke.
Also, those designs seem to suggest that there'll be no great length of time between movies. Rey is wearing pretty much the same clothes that she finished TLJ in and, if there were a year or two or three between films, you'd figure that Kylo would have fashioned a new helmet rather than superglued the damaged one.
