The rainbow sun Mr Onederful design

The word ONE is drawn rather than typed. The O is a round watercolor sun in warm yellow with long, thin rays fanning out around it. The n is a rainbow of three soft arches, dusty blue on the outside, sage green in the middle and terracotta on the inside, painted with a textured watercolor edge. The e is a chunky pale mustard letter. Below, derful is set in a tall retro serif in dusty blue, so the whole thing reads ONEderful.

On the birthday boy's bodysuit or tee, I'm mr sits on top in sage green, making it I'm mr ONEderful. Family shirts lead with a title in large lowercase dusty blue letters, then of mr in sage, so the shirts read mommy of mr ONEderful, daddy of mr ONEderful or grandpa of mr ONEderful. The colors are calm and earthy, a nice change from bright primary rainbows.

This design suits a spring or summer baby, an outdoor party or any family that loves a natural, boho look. The shirts get worn again on beach days and summer picnics.

Planning a sunshine Mr Onederful first birthday

A rainbow sun first birthday is easy to style with the colors already on the shirts: dusty blue, sage, mustard, terracotta and cream. A balloon garland in those muted tones, a large cardboard sun or a macrame rainbow on the wall behind the cake table, and a few vases of pampas grass and dried flowers set a relaxed boho mood. A banner with the words of You Are My Sunshine ties it to the lullaby many parents sing at bedtime, and a few sun-shaped paper lanterns hanging over the table carry the theme overhead.

For food, a cream cake with a little rainbow topper and a sun cookie, a smash cake frosted in pale yellow, lemonade with lemon slices, fruit skewers in rainbow order and sunshine sugar cookies all fit. Small bottles of bubbles make easy favors for the kids. For a simple activity, set out paper plates, yellow paint and ribbon so the older children can make their own suns, or let the toddlers stamp rainbows with sponges in the three colors from the shirts. A guest book where everyone writes a wish for his first year of sunshine becomes a keepsake.

Choose an outdoor spot with soft afternoon light for photos if you can, a backyard, a park or a field. The sun on every shirt looks right at home in golden light.

What the family can wear

Grown-ups can wear their tees with light denim, linen shorts or khakis and sandals, and grandmas might add a cream cardigan. Big kids look cute in shorts and sneakers. For the cake smash, dress him in the bodysuit, sage or tan shorts and a sun hat; later, the baby tee and overalls are easy to play in.

Invite guests to wear cream, tan, sage or denim, so the whole party matches the boho look. If the party is at the beach or a lake, the shirts look great with the water behind, and the sun on the design makes the theme obvious in every photo.

Sizing in the sunshine

Scroll to the final photo on any shirt for its inch-by-inch chart. Adult tees are unisex with an easy fit; stay with your usual size, size down for a snugger look or size up for a relaxed one. For the birthday boy, a 12 or 18 month bodysuit fits most babies at one, and Rabbit Skins is a little generous, so compare one he wears now.
