Please refer to our sizing scale below.

PLEASE NOTE: that a lot of teenagers should use the Adult sizing scale (click the link above to see Adult Sizing) and not the Kid's Onesie Sizing Scale. Generally from ages 12 and up. To give you a guide, size S (Adults) is similar to size 12 Kids (Australian Sizing) in Kid's clothing, and size 140 (Kids) is similar to size 10 (Australian Sizing) in Kids clothing.

Sizing should be worked out primarily by height. Weight can be a factor. As a general guide,  size 120 would be suitable for a 5-6 year old. The correct way to calculate the size is by height (as mentioned above), as follows. If you need help choosing the correct size, email us at  or call  1300 MY ONESIE ():

• Size 120: Suitable for height 115-124cm (45"-49").
• Size 130: Suitable for height 125-134cm (49"-53").
• Size 140: Suitable for height 135-144cm (53"-57").

If you are unsure about the size, we recommend you should go for one size up as it will be more comfortable and long-lasting.

Package Includes: 1* costume and Size reference Product details. (The shoes are not included)
