VTG 70s? Girl's Handmade Shift Dress Size 4? Yellow Chicken in Egg Novelty Print

In good condition, some small spots but these are small (see last photo). Unsure of size, as this is handmade. Please see measurements. I think it's around a size 4, but not 100% sure. The cutest little chick fabric! 

Approximate measurements in inches (laid flat): 
Chest: 14
Length: 20
