These rainbow sun mr onederful adult shirts bring a sunny boho look to the grown-ups when their baby boy turns one. Each grown-up's name sits on top in big dusty blue retro letters, of mr follows in sage green, and then the word ONE is spelled with pictures: a watercolor yellow sun with long rays for the O, a rainbow in blue, sage and terracotta for the n and a soft yellow e, with derful underneath in the same dusty blue, so a Mommy shirt reads mommy of mr ONEderful.

Each adult shirt is Bella + Canvas, unisex, in 100% cotton. Our sun and rainbow were painted in Pennsylvania, and each order is printed in the USA, the inks water-based, only after it comes in.

Mommy and Daddy of Mr Onederful are the two shirts nearly every family begins with, and 22 more family names follow on the menu, Nana, Mimi, Pop Pop, Tio, Godmother and Grandpa included. Custom family name takes care of Great Grandma, Lolo or a family nickname.

Dusty blue, sage, mustard yellow and terracotta suit a boho rainbow or sunny first birthday, and they sit beautifully with pampas grass, a rainbow balloon arch in muted tones and a simple sun cake topper. In outdoor cake smash photos the sun on every shirt seems to glow. We only print the adult tees on white, so the watercolor stays soft.

  • Adult tees are unisex Bella + Canvas, and youth tees are usually Gildan, sometimes Bella + Canvas. Toddler tees, baby tees and bodysuits are Rabbit Skins.
  • Printed direct to garment with water-based inks, so the print stays soft, lasts longer and fades less than other printing methods.
  • Designed in-house in Pennsylvania and printed in the USA.
  • Wash cold or warm, never hot. Air dry or tumble dry low.
  • Ordering for the family: choose a name, color and size, add that shirt to your cart, then change the choices for the next one. Every shirt in one order can be different.
  • Custom names: pick Custom in the Name menu and type the name in the box that appears. It prints exactly as you type it.
  • Fit: adult tees are a unisex fit. Every shirt is printed to order, so we can't take returns or exchanges for size; misprinted or damaged shirts are made right.
Shipping and timing

Every shirt is printed after you order, which takes 2 to 5 business days. It then ships by standard ground shipping and usually arrives 3 to 5 business days later. Orders with several shirts may arrive in separate packages.

We can't add expedited shipping once an order is placed. Need them by a certain date? Send a request and we'll try to help. Full details are in our shipping policy.
Other shirt colors

Each design comes on the shirt colors we chose for it, usually white, or white and black. We pick those colors because the design prints with enough contrast to show up clearly.

Want a different shirt color? Send a request before you order with the design and the color you have in mind, and we'll let you know whether it will print well.

Frequently asked questions

Where is the grown-up's name on the rainbow sun shirt?

On top, in large dusty blue lowercase letters, followed by of mr and the sun and rainbow ONEderful lettering, for example daddy of mr ONEderful.

Is the rainbow sun design only for a boy?

It says mr, so it is made for a baby boy, but the muted rainbow and sun are gentle enough for the whole family, sisters included.

Does the rainbow sun adult tee come in black?

No. It is white only, so the pale watercolor sun and rainbow keep their soft colors.
