Tanktop 01, Brief 01 and Brief 02 are made from a heavier-weight 95% organic cotton and 5% spandex rib.

As part of the development process, the base fabric and dye used for Brief 01 were independently third-party tested for restricted substances, including certain azo dyes and formaldehyde, and passed these tests.

Brief 02 and Tanktop 01 are made from the same type of fabric and dye, sourced from the same Los Angeles textile supplier.

We think of testing as part of material development. When we work with a new supplier or introduce a new fabric or dye, we plan to continue this kind of testing during development.

Machine wash cold with like colors. Do not bleach. Tumble dry low. Do not iron. Do not dry clean. Do not use fabric softener.

To help keep your pieces in their best shape, we recommend washing on a delicate cycle and using a garment wash bag.

Brief 01 has a lower front rise, unbound leg openings for more stretch, slightly more coverage through the back and a slightly narrower gusset.

Brief 02 has a higher front rise, a wider gusset and binding around the leg openings for added reinforcement and recovery.

We currently ship within the United States.

We plan to expand shipping to additional countries in 2027.

The Archive is where earlier Autumn Body pieces may return for a limited time. We think of previous garments as part of the ongoing development of the label, not simply past inventory. Brief 01 is returning from the Archive for a limited time.

We develop slowly and release in small collections rather than on a fixed schedule.

Each piece goes through sampling, fit, material and color development before it is released. We also pay attention to what each garment teaches us once it is out in the world, and use that to inform what comes next.

There is no set number of releases each year. New pieces arrive when they are ready.
