Organic Cotton Baby Onesie - Dim Sum

Size Guide

Your little dumpling will be looking extra steamy in our organic cotton onesie! The chemicals and dyes used by many clothing manufacturers can irritate your baby's delicate skin. To combat this issue, we ensure that the texture of our fabric is as smooth and gentle as it can possibly be against your baby's sensitive skin.

  • Made from soft organic cotton to offer supreme comfort for your little one
  • Our side button-up style available for size 0-3M makes a great option for younger babies to avoid having to pull garments over the head
  • Keeps baby cool and stylish on the warmest of days, allows skin to breathe and prevents overheating
  • Tag-less label to prevent scratching on babies' sensitive skin
  • Available in 0-3M (side button-up style), 3-6M, 6-12M, 12-18M
  • Care Instructions: Machine washable & tumble dry low

Sizing Tip:
Industry standard for baby apparel is to use age as the size, but it is important to measure your child as it is possible to have an older child that still needs a smaller size, or conversely a younger child that needs to size up. If when measuring your child falls into two different sizes between weight and length then it is best to size up to ensure a better fit. Please note that our baby apparel accommodates extra room for a diaper. Measurements are represented with a diaper on.  

We are proud to support Angels for Children. A portion of our proceeds is donated to their project with Bali Kids, supporting pregnant mothers with HIV. To prevent exposing the baby to HIV, these mothers have to undergo a C-section and they are advised against breastfeeding. Your purchase will go towards supporting a mother's medical bill and formula costs and ultimately, will help prevent a child from a lifetime of carrying HIV.

So cute!

I love this onesie! It's super cute and fits well. Was packaged nicely as well. It took a little while to arrive (2 weeks) but likely because I'm from Canada.

Thank you so much for your feedback Melissa!
