To help you here is one of my family images.
The boy sat on the ground is my Grandfather who was born in 1884, the girl next to him b1881 and LtoR standing 1879, 1873 and 1877.
I put this image about 1896 as I put my Grandfather at about 12 and George who is standing married in July 1897 and went to live near London.
Hence the fashions mid Nineties were very different to your image
BTW
This image was also taken in Bradford as was the family gathering I use as my icon.
