From Decades of Style:
"Did women actually cook and do housework in high heels in the 1950s? Possibly even in a girdle and stockings?!? Well whatever the case was then, it won't matter what you wear underneath this FANTASTIC apron from the mid 1950s because all eyes will be on your apron.
This vintage apron pattern is for a smock-style apron with a sweet tulip pocket. All edges are finished with fold-over bias tape.
Pattern includes sizes S, M and L."
