My newest jeans use indigo-dyed warp yarns on the outside and rainbow weft yarns on the inside. A subtle detail that's mostly hidden now, but should become more visible as the denim ages.
@docpop holy moly this is the coolest!
@epu they are Gustin brand, which I have mixed opinions on, but I'm still excited to see how these break in. I bought my pair on ebay, but here's the original listing https://www.weargustin.com/store/jeans-541-the-rainbow-selvedge
