I completed this costume in May 2015 as part of my undergraduate thesis on Spanish traditional costume from Valencia and the Basque Country. It wasn't required, but I did it anyway as a little extra something and because it was fun.
No progress posts since this was about a week-long build only, but I made the red linen skirt, applied the black stripes, and made the bodice based on a Tudor Tailor pattern. The apron and headscarf are made from scraps of muslin and then embroidered. I didn't make the shirt, but really I didn't have time to, and I imported the traditional abarkak shoes from the Basque Country.
Researching this project made me realize that I would very much like to learn the Basque language Euskera. Let's put that down for the hypothetical future in which I have free time.
Included at the bottom is a selfie that I took the day of the presentation, for those who are interested.
