At first glance one might think these ladies could be sisters, just because the woman on the right is young-looking, but really, no, this is a mother-daughter pose. They both appear to be wearing wedding rings, so perhaps the photo was taken not long after the young lady on the left was married. (That sad, wistful expression! And one wonders whether the photographer cultivated the expression, if cultivated is the word, as in, if this was a going-away shot: the young lady is sad to leave her mother, the mother is proud of her beautiful daughter) But the clothes! The daughter: the dress with sailor-style neckline with the striped (blue and white?) collar and cuffs, and the adorable little dark-rimmed hat that we can’t see much of. The mother: goodness (!) the lace is stunning. Is it Broderie Anglaise? And would the collar be described as long-lapeled? I must admit I feel sadly lacking in education when internet-searching for fabric types, styles, etc.
