From the seller:
1900 Ivory Wool Gibson Girl Ensemble: This two piece ensemble was created during the Charles Gibson era in the early part of 1900. It was created out of ivory wool. The skirt has a waist of 24” and a length of 41”. The bodice has a bust of 30” and a waist of 23”. The fabric is sturdy but does have some issues. The skirt has some tiny holes and tiny spots. The skirt has no lining and never did. The bodice has scattered moth holes with a 3/4 inch hole in back. See photo. There is a cotton lining in the bodice which is in sturdy condition with age related wear. The left opening of the bodice front needs a small repair at the ruffle. There is a 2.5 inch tear that is in the gathered area that tucks into the skirt. It is hidden in the gathers so it wouldn't be seen if you repair it. The outfit is sturdy enough to wear and makes a great display piece.
Could this dress be anymore Pollyanna if it tried?
The sleeve style was popular in 1891/1892.
On the left, the dress to the right most of the page has a similar sleeve style to the extant dress as does the pink dress on the right.
The lady above has a dress very similar in style to the extant one. Her picture is from 1892.
