LOL, according to the textes Sarada inherited ELEMENTS from Sakura, but didn't mentioned anything about clothes.
Also, do you think that japanese folks not getting the raws out too already? What kind of logic is that? What do you think, why WSJ tried to ban online reading? Because it also affected the japanese readers too!
Not mentioning it WOULDN'T BE THE FIRST TIME to play with something popular just for fun then kick out to the trash.
Not mentioning that each times when Kishimoto wanted to make a popular theory becoming true he had using at least 30-40 chapter retcons to make them valid. The best example is Obito, where not even the biggest fans of that theory denied that the ONLY reason for it was that Tobi only showed his right eye but never the left, which became bullcrap as Danzo had sharingan in the right side too + Izuna and other Uchihas could be even more logical than a 12 years old weakling who didn't had any reason to become evil.
