This shirt is dyed with Prussian blue, a pigment discovered in around 1704 in Berlin by the chemist Johann Jacob Diesbach.
The pigment is derived from an iron salt and gives an intense, slightly red-cast blue color. it was also used in paintings and can be found in "Starry Night" painted by Vincent Van Gogh and "The Great Wave" by Katsushika Hokusai.
Prussian blue is less predictable than modern synthetic dyes and it's color transfer, inconsistency, irregularity and fading are some of the beautiful natural characteristics of this pigment.
The front of this shirt is cut long and folded up in production to make the front and the pockets out of a single piece of fabric. The fabric is woven with a white warp and the weft is made of a twisted yarn compromised of three threads - white, blue and red, giving the shirt an irregular "dizzy" look. Even though the shirt is over dyed with Prussian blue the color of the weft can be seen through the dye giving the shirt a lively feel.
