I just received a reply from the lady distributor of the rompers.
"You have to tell me the sizes you want and base on the designs you want i will get the sizes for you. Each pack has to be in 1 size.
Meaning if you like Boys number #5 let me know together with the size M."
But she never said which ons is #5, or #6, etc. So do we go from top row, L to R, as #1 - #5, then bottom row, L to R, as #6 - #10?
