Carole Lombard's status as a style leader made her a natural to be one of the stars featured by the Hollywood Pattern company, a division of Conde Nast, and this vintage pattern is currently up for sale at eBay:
It looks to be from the mid-1930s; Lombard is labeled with Paramount Pictures, so it's probably from 1938 at the latest.
The seller describes it as:
"One piece Frock - Dress and Jacket. Sleeveless frock has drop shoulder armhole in one with yoke. Center front opening on yoke is finished with ties. Blouse gathers below yoke and at waistline under tied belt. Collarless jacket has wide lapels and long sleeves in one with front yoke.
"Misses size: 16 Bust: 34 inches."
Here are some more illustrations:
More on the condition of the pattern, which is being sold as is, from the seller:
"In good condition for its age. Pattern is complete with instructions. Envelope has some wear and tear. Instruction sheet is fragile. Pattern appears to still be factory folded. Note: there is a little spotting from age."
Keep in mind, of course, that sizing has changed since the 1930s...which is something you probably know if you collect vintage clothing or patterns.
