Mattel's Chelsea (and friends) and Kelly/Tommy dolls shoes fit Middie, but the clothing does not. Some shirts almost fit with Velcro extensions. And, surprisingly, some Monster High tops and bottoms work.
Clothing made for Lati Yellow fit Middie. Beware the shoes DO NOT fit; Lati's feet are larger.
Jun Planning's Ai BJD dolls clothing fit really well. They can be a little short, but I find this adorable. Some shoes might work on Middie if they are boots. The Mary Janes are way too big.
I am sure there are other items out there besides the above mentioned.
Stargazer, Fossil Hunter, Rockabilly, Muddy Puddles
One doll that shoes and clothing are nearly always a perfect fit is Lottie doll.
Lottie is an UK company, Arklu, that has dedicated itself to creating healthy image dolls for little girls. They are really sweet and have good quality clothing and accessories. These days, that has become a rarity- "good quality, what is that."
Between my daughter and myself, we are up to 8 dolls. They retail for about 20 each- shoes, clothing, and most accessories are a perfect fit. Hats and other head wear obviously will not fit Middie. They work on Petite Blythe! Separate clothing packs are available also that retail for 10 each.
A new series of Lottie's were released recently and some of those are retailing at 25. They have a few more items with them. For example, Stargazer came with a telescope and Fossil Hunter has a backpack, excavating tools, and "fossils." The new Muddy Puddles has yellow rain boots and jacket! I about died from a cuteness overload.
Stargazer, Muddle Puddles, Autumn Leaves
Rockabilly, Pandora's Box
Branksea Festival, Fossil Hunter, Rockabilly, Pandora's Box
I love Lottie's diversity. It make is hard to part with even one doll.
Darwin, Wonderfrog, in Lottie shorts and tights. They are charming even if they are over sized.
I hope to order more soon. I'm starting to think I need them all.
Don't they look like they could be Licca-Chan's little sister?
