The front of the clipping is a dress - an empire sheath trimmed with French rose lace. I found the clipping inside McCall's 3922 - dated 1956.
The dresses are very similar, even though they are 2 years apart. McCall's was quite fashion forward, right? It is a beautiful dress!
I love apron patterns! To be honest, I say that about almost every category of pattern. I love costume patterns. I love toy patterns. I love hippie patterns. I love swimwear patterns. I love patterns for toddlers. And the list goes on and on. But apron patterns! They are the best! m
These are just two apron patterns I've found recently. Both were published around 1955.

The black "Mammy" face on Mail Order 534 is a stereotype which was used frequently in the 1950's. Interestingly, the pattern was published with the same face in a "white" shade as well. I've never come across that pattern. It seems rarer, maybe because the women making aprons didn't want a bland white girl face.
Both patterns and more are available for purchase at DellaJane Apron Patterns.
