i couldn’t find any online, because regular MSD size is too big for my dollies, but it would be nice if you to share some links with me (both boys and girls, cuz both of my BJDs like Lolita clothes) thank you!!!
Not free, but DG requiem has some excellent, well-priced slim mini patterns that should fit the bill. Keep in mind that many patterns for Ellowyne Wilde will also fit minifee and other slim minis. Also found this one. And this one, in a different fabric and with trim, I think would work nicely. With some more digging I'm sure you could find quite a lot more, especially for Ellowyne. As for boys... there are almost no patterns widely available for slim-mini boys. I have taken to just altering girl patterns to suit.
