Here are a few tips to help you pick the right size using this muslin romper size guide.
With Una's long-sleeve muslin romper, you can go up a size if you like — just roll up the sleeves and legs to begin with, and your little one gets more wear out of it over time. Check the photos to see the romper on kids of different sizes. Una's muslin baby clothes run about two sizes larger than standard sizing.
