Alright, Kurenai introduced the Chakra Pulse to Naruto and he immediately mis-fired it, causing the genjutsu of the ninja housewives to vanish. Kurenai didn't mind this because they were making frivolous use of her art, right? We can assume that these ninja housewives use genjutsu to improve their - wrinkles, makeup, bust size, curves, cleavage, and perhaps wardrobe?
Chapter 1:
"I don't usually wear this in the field, though some kunoichis dress in bright colors so they can masquerade as civilian women. Besides, I mask my appearance with a genjutsu anyway. The brightest color I wore as a genin was such a dark red that it looked like brown from a distance." - Kurenai
It just dawned on me that we have no reason to assume that Kurenai looks any different from the way she does in canon, but then here, she masks her appearance with a genjutsu. So what part of her is altered - the only physical description of her I recall of her was about her red eyes and about the clothes she wears in contrast to Naruto's.
