These rainbow sun mr onederful kids shirts are made for the big kids when their baby brother turns one, youth S through XL. A big sister's shirt has sister on top in dusty blue retro letters, of mr in sage and the pictured ONE below; a cousin's works the same way.

Youth tees are 100% cotton, with Gildan our usual brand and Bella + Canvas the occasional alternative; every shirt is made after you order it, printed in the USA with water-based color over our own Pennsylvania watercolors.

Older siblings wear Brother or Sister; Cousin and Friend fit the rest of the gang. A title like Big Cousin goes in Custom family name.

Kids love a sunshine party: chalk rainbows on the driveway, a bubble station, a sprinkler on a warm day and paper suns to color. Wearing a matching shirt makes them feel like part of the family crew. In youth sizes the shirts come only in white, the best background for the muted rainbow.
