Blue Blue Japan Indigo Dyed Sashiko Patchwork Blazer

Size Guide

Indigo Sashiko garment culture brought to another level!

This is one of the most amazing Semi-Casual styles we’ve seen so far. From the lightweight feeling when worn to the geometric woven pattern, you can enjoy this Blazer on any special indigo day.

To create such a pattern, BBJ have used vintage weaving machines to make the complex, textured fabric. Each and every thread will age to a beautiful, lighter indigo shade with nice contrast to the turquoise pattern.

For those who ‘wear a blazer everyday’, it’s time to enjoy the ageing of a well constructed piece! If you want to try an elegant one for work or play days, this is great choice. Look slick in your BLUE BLUE!
