Authentic Since Birth Tee
Identity Collection

Some things were never a performance to begin with.

Small mark at the chest. Authentic Since Birth across the back — plain, stated once, no footnote required. Not a milestone reached, not a version arrived at. Just a fact that was always true, worn the way a fact should be.

The garment. 160gsm 100% organic cotton.

Sensory notes. Lighter-weight jersey than our heavier pieces — soft and breathable rather than substantial; not the fabric to reach for if you want structure or warmth. Print sits as a thin film on top of the fabric rather than dyed into it, a slight edge felt at the design border, most noticeable on first wear and softening slightly with washing. True to size.

Said once. True regardless of who's listening.

Frequently asked questions

Is there anything sensory-specific I should know before I buy — seams, tags, print texture?

Tagless neck label apart from on Toddler items which has a tag you can tear away, printed not stitched.

Print is Direct To Garment (DTG), so it has some texture rather than a plastic-feeling transfer.

We're building out a full sensory spec page — for now, message us and we'll tell you anything we know.
What if it doesn't work for me once it arrives?

60 days, no arguments. Wear it, wash it, live in it — if the fit or feel isn't right, we'll exchange it or refund you. You don't need to explain why.
How long will it take to arrive?

Typically 3 - 5 business days. However, everything is made to order so delays can rarely happen. You'll get tracking as soon as it ships.
