Hello Esther
I'd go along with Gadget,early 1890's.Girls fashion did mirror that of adults
and here you can see the raised shoulder and shorter cuff,a fashion emerging at this time.
She still has the lace collar of a child.
It wasn't usual for girls to have short hair,it may be she suffered a long term illness where it
was usual to cut hair short in order to make it manageable.She does look a bit peeky,there's
no light in her eyes is there.
