At Wonsie, we know that every person is unique and may not fit perfectly into a standard size range. That's why we offer a range of sizes to ensure that we have a bodysuit that will fit your loved one comfortably.

The numeric size of our garments is a rough indication of the age of a child, but if you're unsure which size to choose, we recommend sizing up, especially if your child is taller than average or wears a nappy.

Our larger sizes (12/XS, 14/S,16/M, 18/L and 20XL) are sizes aimed at teenagers, adults, and the elderly.

To find the best size for your child, we recommend consulting our size chart and paying special attention to the length of the torso. This is the most accurate measurement if your child doesn't fit perfectly into one of our size categories.

Please check sizes on actual listing information for specific measurements

If you need to exchange your garment for a different size, please familiarise yourself with our exchange policy and don't hesitate to reach out to us at if you have any questions about sizing.

We are always happy to help.
