Dagy Doll is made by Gold Mountain Toys which is sometimes abbreviated as GM. Dendi Star is another GM doll that looks the same as Dagy. I don’t know why they were marketed under different names. It may have been based on location of sale or on the time of creation. Doll companies change the names or rebranded their dolls usually based on market research, but sometimes just on a whim or a hunch.
Looks like she hangs out in a European Disco in the 80’s. She has fully rooted top eyelashes. Often they are broken due to age. Looks like a cross in between an Italian Tanya Doll with eyelashes and a Shillman Doll. Any doll made by GM is sure to be a cute doll. I have seen a few turkeys, but I wonder if they are in the wrong box. I think the dolls are from the late 70 to early 80s. I have not seen any from the 90s. The ones you will find online will be expensive due to the fact that if a reasonably price doll appears she will be sold right away leaving only the way over priced dolls. Prices range from $100 to $300.
In order to find her you will have to look at online sites such as eBay, Etsy, and Mercari. You will need to set up some kind of alert system or look for Dagy and GM Toys at least once a day. If you have friends in Europe they can help you because many dolls of European origin are sold only to Europe due to Covid restrictions or other issues with packages being lost or with overly high costs for shipping. If you make doll friends on Facebook, they could also help, and you may be able to set up a trade for a doll that they like in return. But a word of caution Most people will not let a Dagy go if they have her because they look so good.
Other notes: I don’t know what the name Dagy means. They were mostly sold in German, Italy and Switzerland.
In order to be sure you are getting a real GM doll there is a trade mark on the back of her neck. The body only says Hong Kong on her back.
Outfits for Dagy and Dendi Star are very hard to find. This one is labeled Alta Moda.
