VINTAGE Baby Girl's Dress Approximate 12 mo-HAND SMOCKED-Polly Flinders Label

So cute!!  Baby girl's dress is pale yellow cotton hand smocked and has apron string ties.  The bottom is a very full skirt.   The label reads "Polly Flinders".   CONDITION:  Unfortunately, Fair condition.  No  tears, holes, etc. noted.  There are some dark yellow stains on the skirt.  I have no idea what the stains are from.  I have washed the dress, but no attempt to get the stains out.  I think they are permanent.  see photos

Measures approximately as follows:

chest = 18"
shoulder to hem = 14"
