Printed on an authentic Comfort Colors 1717 tee, this shirt is soft yet sturdy, pre-shrunk for reliable fit, and finished with twill-taped shoulders and double-stitched hems for years of wear.

Why Made-to-Order is Better for the Planet 🌎

When you choose made-to-order products, you're making an eco-friendly choice that helps reduce waste and pollution. Traditional mass production results in millions of unsold garments ending up in landfills or being incinerated, releasing harmful toxins into the air.

By only producing items when they’re ordered, we eliminate excess inventory, reducing textile waste and lowering the environmental impact. Plus, this sustainable approach conserves resources by avoiding overproduction.

Your purchase supports a smarter, greener future—one where fashion is made responsibly and only when truly needed. Thank you for making a difference!

As every item is made specifically for you, we usually can't accept returns unless the product received is defective or is not what was ordered. However, if you have any issue with your item, contact us we will be happy to help in whatever way we can. If a return is authorized, we will provide shipping instructions and the address of our returns facility.
