Anthro Dolly:Which body shape fits her more?

I practiced with body shapes and things today and I can´t decide her anthro  body type,since she likes sweets it would be logical if she would be lil  bit chubby but she is really childish and not grown up it would be logical if she is flatchested and kid a like body type.
I drew them with top shirts so you can see their figure better.I would never wear that because of my body shape..but yeah

I liked drawing the chubby version of her,and that figure is based on my own body shape so I think it looks realictic..but Im not sure does the skinny one looks realistic..she is flatchest and slim..so probaly likes to work out?And the chubbu one Dolly is just kind and likes sweets and doesn´t really care about working out.
SO WHICH ONE YOU LIKE ON HER MORE?
HAVE A LIL TEXT AS BOUNUS.XD
