Size Chart


It doesn’t get much cuter than this – except when your little one is wearing it! If your child is about to become a big bro or a big is they’ll surely want to let the world know, and you’ll be itching to announce your new arrival as well.

This high quality t-shirt can be customised with your due month and year, making it an extra special piece for the entire family to enjoy. We simply love this shirt for social media announcements, and the lovely material will allow it to be a keepsake for years to come – even if your little one does want to wear it everywhere.

Choose from a vast range of colour customisation options to allow this shirt to seamlessly blend into the theme of your announcement.

Our t-shirts and onesies are made from a beautiful, thick, 100% cotton fabric that is super soft and comfy - perfect for delicate baby skin. The T-shirts are available in sizes 000 – 5 and onesies in sizes 0000 – 1. Press stud buttons are used in the shoulder of all onesies and for T-shirts sizes 000-0 to make dressing your little one a breeze (well a little easier). Our T-shirts for older kids (sizes 1-5) have a stretchy neck to make getting it on and off easy. Consult our sizing chart for further information.
