At MAYWA the majority of our product comes from Korean suppliers and manufacturers. Korean sizing tends to run slightly larger than UK sizing so normally there is no need to size up.
We have included a size guide below with measurements to help you.
If you need any help with sizing please contact us via email at firstname.lastname@example.org and we will be able to guide you as to which size will fit your child. We also offer a 30 days returns policy in the instance you need to exchange for a different size.
