1930s - 40s Vintage Three piece Art Deco Hand Made Clothing Set "Dress / Apron / Slip"

I recently bought an old suitcase from an auction and found this clothing inside.  It all looks to be in wonderful used condition.  I'm a guy so please don't ask me about sizes, its all hand made and there are not any tags inside.   It remines me of what a farm house wife may have worn back in the 1930s or 40s.  

If anyone has any better idea about the age of this clothing or a better way to sell it I would be most grateful.
