Dolly Darling Original Barbie Clothes Kits

 I spotted these interesting kits a few weeks ago at a reasonable price. A quick search found a few listings for reproduced "Dolly Darling" patterns, but no original patterns or kits. I took a chance on them and when they arrived in the mail, I was not disappointed. I bought 3 kits and each one contains patterns, fabric, and trims to make about 5 Barbie Doll outfits. From the styles shown, I think these are from the 60s. 

 Here is a flyer that was in one of the kits. It shows some of the available sets. Notice the original price of $1.50 per set or any 3 for $4!

 This is the "Bridal and Honeymoon Ensemble" which has patterns for: Sweet Dreams nightgown, Inside Story lingerie, Off on the Honeymoon suit, Lacy and Lovely robe, and the Bridal Gown. The fabrics, trims, and patterns are shown below, but I didn't want to take them apart too much for photos.

 This set has a Mix and Match pant/skirt suit, Suited for a Busy Day suit, Evening Glamour gown, Cover Story coat, and Anytime Dress up Dress. Below are the patterns and fabrics.

 This "Here Comes the Bride" set has more fun pieces for: Off on the Honeymoon, Dinner for Two, Lady at Home, Fancy Foundation, and the Wedding Gown and Veil. Below are its parts.

I think you can find almost anything on the internet, but I could not find any information about the history of these patterns or any originals offered for sale. There are plentiful copies available on ebay, but I didn't see any of my sets reproduced. 
Does anyone remember these kits? They are from before my time, so if you know anything about them, please leave a comment or send me an email; I'd love to know more about them!
