FAQs
How do I choose a size?
Onesies are sized by height, not clothing size. Adult S suits 155–160cm up to XL at 170–175cm, and kids sizes 100–140 match height in centimetres. If you're between sizes, size up.
How fast will it arrive?
Orders are dispatched from our Melbourne warehouse in 1–2 business days with tracking. Melbourne metro orders usually arrive in 2–3 business days, and regional areas and other states in 2–8 business days.
What does shipping cost?
Flat-rate standard shipping applies Australia-wide, and it's free on orders over $140.
