To find the right fit for your little bee we always suggest starting with our sizing chart!  While all bees are different sizes and shapes this is a good place to start. 


Keep in mind that our PJ's are made snug-fitting since they do not have any flame retardants!  If you want to talk through the best fit, reach out to a team member we are happy to help
