This dress is 9.5'' long. The shoulders are 3.5'' wide and the full sleeves are 4.5'' long. Armpit to armpit measures 4'' across. The back has a two button closure , The neck and cuffs have lace trim. The silky deep teal fabric has a bit of a sheen. The pinafore is made of cotton batiste with tucks, gathers and lace trim. It has a one button back closure and a sash to tie in a bow.
My guess is that this dress would be good for a doll in the 16'' range. This may be an old Gabriella dress.
