Our Story
Printed In-House, Made With Care
Lil Croptops started with a simple frustration: kids' graphic tees that faded after three washes, felt like cardboard, and were printed who-knows-where. So we bought a press, learned the craft, and started making them ourselves.
Printed In-House
Every garment is designed, printed, and packed in our studio. No third-party print farms.
Made With Care
We choose soft, durable cottons and test every graphic for comfort.
Small Batches
We print in small runs so designs stay fresh and waste stays low.
Printed In-House, Made With Care
Why We Print In-House.
We started Lil Croptops because we were tired of ordering cute designs online and getting prints that cracked after two washes.
So we brought printing in-house — every onesie and tee is produced and checked by our own team, not shipped out to a third party. It’s slower. It’s also the only way we’d put our name on it.
