page from Supergirl vol. 5 #5 showing Supergirl being undressed by her father, Zor-El, as she's walking naked to her pod and saying "Love to, daddy." she is super thin and her ankles are so tiny they should snap, her foot looks like it's a hoof, thin wisps of smoke cover her private areas, with extra blurring clearly added in post to cover them up more
panel from Supergirl vol. 5 #3 showing evil Supergirl (in a black version of Supergirl's 2 piece suit), her top clings to her clearly bralass breasts and cuts off just under them, her torso is exposed going down to her pelvic area where her skirt hangs under her hips bones as a frilly belt, the real Supergirl lies behind her
panel from Supergirl vol. 5 #1 showing Supergirl and Power Girl flying at each other ready to fight, except both of them are facing toward the audience viewpoint, so neither of them are facing towards each other, Supergirl's leg is pushed up at her knee high in the air to cover her crotch area as we're looking up at both women and would see up her skirt, her body is turned away from Power Girl, and vice versa for Power Girl, their arms are already outstretched but neither are connecting with the other

Revisiting the infamous Crustacean Supergirl Run

Somebody in the Supergirl wearing a frilly belt post mentioned that at least she was muscular and looked strong.  This was actually later in the Ian Churchill Supergirl run after he had been told specifically to draw her thicker and not give her vacuum sealed tops.

This is what she looked like earlier in the run.
