me, realizing that the progression of junko's clothes in ttlt grow steadily more masculine.
in oaei, she's still in fashionista mode. even dressed down, she's a model, she's high femme.
in oafc, ryoko is in a literal suit. it's tailored to her, so it still has feminine aspects to it, but it's intentionally blurring the lines. (the text goes so far as to imply that ryoko would prefer something more masculine than junko did, among other things.)
in oalh, she is literally in a specifically male kimono. (only. minus the part that would be called a kimono.) she's wearing hakama and a haori. the hakama - the specifically pants not skirt hakama - is, as far as i know, specific to the male version.
junko out here intentionally blurring gender lines the more fully herself she is.
