I don't think they count as bjds so I will post this here: does anyone know where to buy 2nd hand Pullip doll clothing? Or is it possible to order the outfits and not the whole doll?
Pullip are Off Topic but you can ask about them in Brigadoon. I'd recommend you check out Mandarake and Dollyteria. Both places are in JP and sell various doll clothing sizes second hand.
Pullip clothes are not sold separately. Their clothes are only sold with the doll, so your only option would be to look for them secondhand, like in the places mentioned above. However, secondhand Pullip clothes seems to be rather rare. I often browse Mandarake and Dollyteria and don't really recall seeing any Pullip clothes... There are lots of Blythe and Licca clothes, but not Pullip. Pullip can wear Blythe clothes (when I was into Pullips, I bought them clothes made for Blythe) and I think Licca clothes as well, but I'm not sure about the latter.
Sometimes I have seen Pullip outfits sold separately on Ebay. . . But it is luck of the draw on what is being sold. If you are not looking for a specific outfit, then Etsy is still a pretty good place to find custom Pullip clothes as well.
When I lived in Japan, I bought the Volks "Who's That Girl?" line of clothing for my Tae Yang dolls. Barbie/Ken clothes also fit them. I did go to one kind of doll hobby store in Akihabara and found a doll I wanted and not his clothes but I don't know if those kind of stores have online presences.
That's what I was afraid of. I'm mostly looking to collect the Cinnamoroll outfits that they've made so I think I have my work cut out for me
