I was surprised how pretty and good quality the dress is. It's not typical magazine "furoku" quality but it was made of a real good material (seems like cotton) and the collar lace is very beautiful. It's free size and it fit me fine even if I'm taller than most Japanese.
The book itself was quite small, but still filled with a lot of lovely images. 5 stars for me, because the dress was the reason why I bought it, and it is perfect.
