Each birthday t-shirt is made using a high-quality 100% cotton short-sleeve tee, chosen for its softness, durability and comfort against young skin. The cotton is ethically sourced and suitable for everyday wear, making it ideal for active children and repeated washing.
The rainbow motif is created using a chenille fabric patch, giving a beautifully tactile, raised texture that feels soft and cosy. A subtle gold glitter detail is incorporated into the rainbow design to add a gentle sparkle without being scratchy or uncomfortable.
The personalised age number is applied using professional-grade heat transfer vinyl, carefully hand-pressed in my UK studio to ensure a long-lasting finish that stays secure through wear and washing.
Care instructions
- To keep the t-shirt looking its best:
- Machine wash at 30°C
- Wash inside out to protect the design
- Do not tumble dry
- Do not iron directly over the decoration
- Avoid bleach
Following these care instructions will help preserve the colour, texture and sparkle of the design, allowing the t-shirt to be enjoyed as both a birthday outfit and a keepsake. Each item is made to order with care and attention to detail, ensuring a thoughtful, well-made garment designed to be worn, loved and remembered.
These personalised birthday t-shirts are available in a range of children’s sizes to suit different ages. Each t-shirt is designed with a relaxed, slightly generous fit to allow for comfortable movement and easy layering. Exact garment measurements are shown in the product photographs.
For the best fit, we recommend comparing these measurements with a well-fitting t-shirt your child already owns. The t-shirts are lightweight and easy to wear, making them comfortable for all-day celebrations, parties and play.
Each finished t-shirt is letterbox friendly when folded for posting, making it ideal for gifting directly to the recipient. If you’re unsure which size to choose, sizing guidance is included in the listing images.
