It's
dyed using a Japanese stitch resist tie-dye technique called
"Shibori".The section of the fabric is hand-stitched or hand-tied before
being dyed, resulting in polka dot style small circles (the section
being tied appears in white and untied section appears in colour). This
is all done by hand. You can see the crinkled texture created by shobori
dyeing. If you look closely, sometimes you can see the needle holes
where the fabric is stitch-tied before being dyed. No two dots are the
same as they're all individually hand tied.
Shibori has been very
sought after in Japan for centuries, and new items can be very
expensive. Please see photos for details, the text is from books on
Japanese kimono design and Shibori. The last photo shows an antique
kimono dyed using shibori technique in V&A Museum, you can see its
description for reference.
You can see this video for information on how shibori is made:
