is this the same author or just the artist of the miss is not a side kid. the drawing is so identical. Even the characters look the same but now they have different roles.
@bunny-k1m it actually has an easy trick/excuse that can be used. The skinner a person is the taller they look. This is why they prefer very skinny models. The clothing looks better cuz it is longer. It already is long but the figure/shape of the person can help to make things look longer/taller. The more thicker/fatter (some people have a natural thick body structure and some others just have extra fat) the person is, they look shorter.
Having that in mind, we could say that the MC was average a bit taller than average but not tall enough but looks shorter cuz she was obese. Of course the artist made some adjustments but the over all is that. an optical issue works that way. The artist is just using that excuse to actually transform the MC into a new body but with the same characteristics of her when she was fat.
