Why I can’t find the right clothes for my BJD?

Your doll might be too slim. You can either make do with what fits or find a custom maker. There are many sellers in the BJD community who offer custom outfits, or you could make your own. If you care a lot about finding the perfect fit, it’s best to go for a doll with sizes similar to Volks’ SD, SDGr, SD16, MSD, or YOSD, as these sizes are commonly used in the BJD clothing world.
