Christening gown

Gifted to my family in 1952 when living in the UK for my Father's Christening. The story goes that apparently the dress was much older when it was received by the family. Some say it could be made in the early 1800's but I am unsure and would like to get an idea of how old the gown really is. It used to have lots of petticoats, but my Nan had to use them as nappies for her children so it only has 1 petticoat left which has been mended by my family across the time.
