Here are 3 from my collection of Victorian/Edwardian photo cards otherwise known as cdv's the larger ones are known as cabinet cards.
This dress has quite a lot of covered buttons, lots of lace and the usual brooch worn at the neck.
This dress is very similar to the first i presume they are sisters? notice that the sleeves have the same design.
This dress i think is slightly earlier than the other two because of the volume of material used for the skirt, again she is wearing the lace collar high with a brooch.
