But aren't all changes in character design that aren't supported by timeskip sudden? A character who looked static for more or less an entire arc gets a design change at some point and it wasn't foreshadowed or anything. Especially since some other characters retain the same style without change. I mean, do we actually expect the hairstyles and such that occur whenever they don CS clothes? Those seem pretty sudden to me. If Erza decided to wear a ponytail with her default Heart Kruz armour all the time, I would consider that a pretty sudden change. Juvia's changes were always sudden and one occasion was immensely unbelievable.
