Butterick pattern 4410 in a size 7-8-10. Breast 26-27-28 1/2
Pattern is partially used. It was originally made for a 7-8-10) size range but it was used to make for a size 8 and this eliminated the cutting lines for a size 10. You could just add on for the bigger size since all lines seem to be always evenly spaced from each other.
The pattern is complete.
Very loose fitting slightly flared robe, ankle length, top or nightgown has yokes and long sleeves. Pants have elastic waist, no side seams.
I know for sure the robe is unused and sometimes the multiple size patterns are hard to describe accurately but the pieces are all there.
