Big Brother & Big Sister Shirts

Order big brother and big sister shirts online to celebrate a new sibling, plan a pregnancy announcement or bring the family together for a photo. Explore Garden Club, Sunshine Club, Wildflower, Bright Days and First Friend designs, with Big Bro, Big Sis and selected Little Bro or Little Sis versions. Choose the wording that fits each child's place in the family, then build a coordinated outfit one tee at a time.

Every design keeps its original kids tee option. Additional garment options have their own size charts; check the selected product measurements and size labels before ordering. Check the garment measurements before ordering; these labels are not US ages or toddler sizes. Each listing is one shirt, so matching sibling shirts are selected separately. For personalization with names, use the optional requested wording field and check the details in your proof. Review your digital proof before production.

Pregnancy announcement ideas with sibling shirts

A big sister announcement shirt or a big brother shirt gives the older child a visible part in sharing the news. For a simple photo, let the sibling wording be the focus and keep the background uncluttered. You could photograph the child holding a handwritten announcement card, or capture the family's reaction together. Choose a design the child will enjoy wearing after the reveal, too. If you are searching for a promoted to big brother shirt, compare the pictured Big Bro designs: the available artwork uses its own shown wording, rather than automatically including that exact phrase.

Choosing sizes for kids and toddlers

Start with a shirt that currently fits the child. Lay it flat and compare its body width and length with the product's centimeter measurements. The five available labels are 110, 120, 130, 140 and 150; the size chart runs from 32.5 cm wide and 44 cm long to 42.5 cm wide and 59 cm long. These are garment measurements, not chest circumference or age recommendations. Toddler labels such as 2T and 3T, infant sizes and baby bodysuits are not listed in this range. If the smallest measurements are too large, contact us before ordering rather than assuming a Little Sis or Little Bro design comes in a baby fit. Explore the kids' clothing collection for other styles and check each listing's own chart.

Planning matching sibling shirts and family sets

Garden Club and Wildflower offer Big Sis and Little Sis designs, while Sunshine Club and Bright Days offer Big Bro and Little Bro versions. First Friend includes Big Bro and Big Sis options. Coordinate the design theme, choose a color for each child and add every garment separately. Matching does not require identical sizes: measure each child independently. For parents or other relatives, browse T-shirts and hoodies, then contact us about coordinating artwork before ordering those garments. Adult versions of these sibling designs are not included automatically, and each product listing represents one garment rather than a complete family set.

Personalization with names and reviewing your proof

A name can make a sibling outfit feel more individual. If you would like a child's name, a year or a short message, enter your request in the optional requested wording field on the product page. The products shown here have preset designs, so review how any added wording works with the selected artwork in your digital proof. Keep the spelling and intended sibling role clear when explaining what you want. Check the name, design and placement carefully before approving production. If the shirts are for an announcement or family event, include the intended date in your inquiry so timing can be reviewed. Ships worldwide, with delivery estimate below.

Big brother and big sister shirt FAQs

Which kids’ sizes can I order?

All ten sibling tees list sizes 110, 120, 130, 140 and 150. Compare the flat garment width and length in centimeters with a shirt that fits. The numeric labels are not US age sizes.

Are these shirts available in toddler or infant sizes?

The current range does not list infant sizes or toddler labels such as 2T and 3T. Little Bro and Little Sis describe sibling roles. Check the measurements and contact us if you need a smaller fit.

Can I use a shirt for a pregnancy announcement?

Yes. Choose the Big Bro or Big Sis design you want for the older child, then check its exact pictured wording. The shirts can be part of an announcement photo without adding a date or changing the artwork.

Do matching sibling shirts come as a set?

No. Each listing is one tee. Add each sibling’s design, color and size separately. Garden Club, Wildflower, Sunshine Club and Bright Days have coordinating big and little sibling versions.

Can I personalize a shirt with a name?

Use the optional requested wording field on the product page to request a name or short message. Check the spelling, design and placement in your digital proof before approving production.

How do I check delivery timing?

Ships worldwide, with delivery time shown at checkout. If the order is for a particular announcement or event date, contact us before ordering so the timing can be reviewed.
