Thank you
And yes, I made the dresses The pattern is two slightly pleated rectangles (There should be the pattern and instructions here (Google drive link))
The chairs are mobile phone chairs - I got them off eBay, but I've seen places like Mimiwoo selling them too. The stuff in the background of the first pic is mostly re-ment, the blue chair was a random decoration from Debenhams (a UK department store), and the desks are acrylic blocks supported on more re-ment. They have another room with dolls furniture from Ikea
The classic faces were a bit more angular and I think a little larger overall than the current ones (called cutie faces).
