This should be two separate things. Petite sounds like someone who’s of age but is built relatively like a child (small height, small build, etc.) While loilcon is the same but the person is actually underage
Love Mr Joker below me XD
I downvoted because they are two separate things. A petite character doesn't have to be loli, and vice versa. There are puchalolis and oppai-lolis. There are petite adult women with adult looking faces. I could go on.
