✨Product Details

Share the news with a personalised big cousin reveal T-shirt in shades of pink. 'PROMOTED TO' curves above 'BIG COUSIN', with your chosen date underneath and a small pink star below it.

Wrap it for your niece or nephew to open beside an announcement card. They can wear their new title at your next get-together, sharing the excitement before they meet their baby cousin.

How to Order

  1. Choose your preferred relationship and colour option from the dropdown.
  2. Select your garment and size from the available dropdown options.
  3. Enter the complete date phrase in the personalisation box, for example 'Est Jan 2027' or 'in January 2027'. Replace the sample date with your own and include only the prefix you want printed.
  4. Enter only the wording you want printed. Contact us before ordering if you want to change another part of the design or its layout.
  5. Check your selections, spelling and any date, then add to basket.

For a pregnancy announcement: Our newborn baby vest is the most popular choice.

For a more premium feel: Choose a baby grow with integrated feet for a complete outfit and a keepsake of your announcement.

For a budget-friendly option: Our one-size bib offers the same personalised design at a lower price.

Baby vests are available from newborn to 12-18 months, and baby grows from newborn to 6-12 months. If you would like your baby to wear the outfit later, choose the size for when you expect to use it. Check our size guide for measurements before ordering.

We understand that some moments are meant to be shared on your terms. Whether you’re planning a surprise announcement or keeping your news private a little longer, your order is handled with complete discretion from start to finish.

All items are shipped in plain, unbranded packaging, with no indication of the contents inside.

Your special moment stays yours until you’re ready to share it.

Q: Will Est be printed automatically before my date?

A: Enter the complete date line you want printed, such as 'Est Jan 2027' or 'in January 2027', using your own date. Include only one prefix so both 'Est' and 'in' are not printed.

Q: Can I return a personalised item?

A: Personalised items can't be returned unless faulty or we've made a mistake. If there's a problem, contact us and we'll put it right.

Q: How should I wash the garment?

A: Wash at 30°C inside out. Do not bleach. Tumble dry on low and iron on the reverse, avoiding the print.

Q: Will the print last through washing?

A: We print directly onto the garment with ink designed to stay vibrant through repeated gentle washes. Follow the care instructions to help protect the print.
