Overview & Benefits

Create coordinating Halloween outfits for brothers and sisters with personalised initial clothing.

Choose Big Brother, Little Brother, Big Sister or Little Sister, then select a children’s T-shirt, baby vest or baby grow. Every role is available on every garment.

Each garment is sold separately.

Celebrate Halloween together with personalised sibling clothing created especially for brothers and sisters.

Each garment features the child’s own large Halloween initial, surrounded by delicately illustrated pumpkins, ghosts, bats, cats, lanterns, spell books and autumn foliage. Every letter from A to Z has a different arrangement, giving each sibling an individual design while retaining the same coordinating watercolour style.

Choose from Big Brother, Little Brother, Big Sister or Little Sister wording, then add the child’s name and required Halloween year.

The muted orange, olive green, purple and neutral palette creates an autumnal Halloween outfit without relying on bright novelty graphics.

Please Note

The price shown is for one personalised garment.

Product photographs may show two garments to demonstrate how the designs coordinate. Each Big Brother, Little Brother, Big Sister or Little Sister item must be personalised and added to the basket separately.
