✨Product Details

Surprise your daughter with a personalised 'Promoted to Big Sister' T-shirt. Pink outline lettering and a small star sit above your baby's expected arrival date.

Give it to her when you tell her a little brother or sister is on the way. A toddler big sister can wear the T-shirt on a visit to relatives, letting her new title reveal the news. A design option is available for a baby-sized reveal gift.

How to order

  1. Select the sibling or cousin phrase from the dropdown.
  2. Choose your garment and size.
  3. Enter your date wording, for example 'Est December 202x', in the personalisation box.
  4. Include any other wording changes in the personalisation box.
  5. Check your details and 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: How do I choose Big Brother or Big Sister?

A: Select your preferred sibling phrase, such as Big Brother or Big Sister, from the dropdown. Use the personalisation box for the date, where applicable, or other wording changes.

Q: Can a child wear this T-shirt for the announcement?

A: You can give the garment as a reveal gift for an older child to open. A toddler who is becoming a big sister can wear the T-shirt to share the news with family. Check the available size information before ordering.

Q: What does the 'Est' date mean?

A: 'Est' means 'established'. Add the date when the new sibling is expected, for example 'Est December 202x', to mark the start of their new role.

Q: Can I return a personalised item?

A: Because every item is made to order, 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: How do I help the print stay vibrant?

A: Follow the washing instructions and avoid ironing directly over the print to help protect it through repeated gentle washes.
