“Official Dress of the Court of Annam”, a series of 54 paintings by the court painter of the last Nguyen Dynasty.
Painted during a period of French colonial administration, the style is a blend of traditional Chinese painting (see the similarities with the style and this Qing painting of Qianlong) as well as a modern and more western style (Painted in watercolour and gouche, also note the realistic perspectives of the first painting)
Here is a link to see more of it as well as other details of the book.
Unfortunately, I am not able to find a digital copy online but the National Gallery in Singapore has a copy as well as digitized scans of the pages at the gallery.
