Will my body type stay the same throughout time?

If I weighed 116 and I gained weight and then lost it would my body look different then it would have if I never gained weight and then lost it? Like if I used to have really skinny calves and I gained weight and had chunkier calves for like 4 years if I lose weight will my calves be really skinny again? I am 24.
