There’s something about indigo that always feels right this time of year. Maybe it’s the way the rich, inky shade brings out a calming vibe or how it adds depth to even the simplest outfit. Inspired by vintage workwear, washed denim and faded military fabrics, today’s indigo pieces bring texture and character without feeling overly precious. And when you layer different shades of blue together—from breezy navy outerwear to cobalt-tinted shades, the whole look feels cool and considered.

The key is mixing tones and materials so the outfit doesn’t feel too matched. A naturally dyed patchwork pair of pants, a relaxed slub cotton tee and maybe a well-worn washed chambray shirt creates the foundation, while accessories in contrasting shades of blue add some nice dimension. Together, the result is a monochromatic outfit that’s easy to wear, but visually rich in a way only indigo can deliver.
