The Dao have up to 9 local subgroups. Each has its own traditional costume, the different features helping to distinguish one subgroup from another like the color of the headscarves and the particular way of tying it. The women use indigo to dye their costumes and the batik technique to create beautiful patterns.
I met this woman from the Red Dao in 2012 in Tả Phìn Village. The intricate embroidery and beading on her costume really gives one a sense of how much patience the process requires. This photo of her – which was taken in her kitchen -, is one of my favorites so I decided to go back to give her a copy as a gift. During that second visit, she was kind enough to show me the indigo dyeing process.
