The 12M fits our 10 month old well worn on the first set of clips and without rolling the pant leg (baby's height is 73cm so on the taller side).
I bought the same cotton twill pants in 4T for our 4 year old so they could sometimes match this fall and winter :D
I'm very pleased so far as baby can easily crawl in them both on hardwood floor and the padded playground, and they're not restricting when he stands up and down.
And of course, they're so cozy looking paired with a sweater!

These overalls are such a good fabric. Light enough for summer, but heavy enough to transition into the fall. They are the cutest overalls. I can't wait to see how long they will fit my 1-year-old!

My baby is super tall for his age and I love that these overalls will stay with him for awhile. The craftsmanship is great. They are super cute on baby and there's plenty of room to grow.

I usually have a hard time finding good overalls, I worry about them being too hard to change a diaper or even check to see if a diaper needs to be changed. All those fears I had were silly, not only are these overalls easy to pull up and down without having to unbutton the straps; they also are stretchy enough in the back to check to see if a diaper change is needed! Can’t wait to purchase more during the fall❤️
