Personalised First Birthday Under The Sea Sweatshirt, 1st/2nd/3rd Birthday Jumper

Celebrate your little one's special day with our Personalised Under the Sea Birthday Sweaters!

Available in sizes from 6-12 months to 5-6 years, these sweaters are perfect for children of various ages. We can customise them with any age up to 5 years old.

Our premium printing process directly embeds the design into the fabric—no transfers or vinyl—ensuring a durable, long-lasting finish.

Proudly crafted in our Essex countryside studio, we use the latest printing technologies to create high-quality garments. Unlike vinyl or stickers that can peel or crack, our designs are made to endure, so your child can wear their special sweater time and time again.

For best results, wash inside out at 30°C, then hang to dry or tumble dry on low. Always iron on the reverse to maintain the vibrant colours.

Make their birthday extra special with a sweater that's as unique as they are!
