I saw the cover, I was so confused up till this point
@MasterGeo0X It's a matter of the translation and probably budget cuts while making the manga. Japanese have very specific male pronouns but no very specific female pronouns unless your intimate with the person.
@IrregularPerson i just re-read the WN chapter and it was just like the manga, the princess look at toddler Ash and assume that was a normal way to dress, so she just take all the elements of Ash clothes Set and make it one (Lol). The only thing is not well explained is a little detail about how Ash see the little girl clothes as a way to train his spirit, welp Ash being Ash as his best.
@dezzot Franklin D. Roosevelt grew up during an era where boys wore pink and wore dresses. It was a thing apparently before WWI, and yes there's a picture of that U.S. president as a kid wearing one. Just thought to add that quip to what you said.
