This is a vintage Simplicity Pattern #2681 - Misses Dress with Belt. Very Cute!
Size 14 - Bust 34 - Waist 26 - Hip 36
Pattern is cut, but has all pieces except for N - sleeve view 1 (missing one piece shouldn't make the pattern impossible to sew - so still very functional). Package is in bad shape with rips, but the pattern itself is functional and all the needed text/pamphlet are in tact.
