When I first read this part of the manga way back in the day, the translators/publishers censored Marm's amudo design by blacking out her legs so that she's wearing pants instead of bloomers. (It's a conservative country prone to this sort of censorship in case people want a reason)
And the funny thing about that censorship is? I actually think that it accidentally improves on the original design. The black pants design fits well with Hyunckel's own amudo look and makes it look like Lon Berk placed some armor on Marm's legs.
Just stating my personal preference here. But I can already hear the pained shrieks of a few people because I supported the censored look of a character's design ^_^
