hmmmm im gonna be honest this feels very dumb lol. scrolling through google results i have to say...they all seem equally feminine looking to me? the cancers don't seem "motherly" looking, at all, except maybe princess diana? but that could just be because i'm associating her with her reputation idk. i'm a cancer myself tho and i wouldn't call myself or any of my cancer friends "motherly" looking.
so in conclusion i think you're just being silly tbh.
zodiac signs don't make you look masculine or feminine, or....motherly.
