I hate it when some say RV members have a similar look and some jump and say "GUYS each girl has a COLOR! you can tell who's who by the color they're assigned to!!"
Like, yeah, if people are gonna need colors to tell them apart...that means one thing.
Frankly, it's not THAT hard to tell them apart. You struggle at the very beginning, cause the girls have a similar vibe (lord KNOWS I struggled with Irene/Seulgi/Wendy for like a week when they debuted) -- but then you realize they look different
