This collection is a combination of the regular and the outside seams designs.
Sizes Newborn, 0-3 and 3-6 months are designed with outside stitching to provide extra comfort, protect baby skin and avoid irritation. These smaller sizes also have double layered ribbed mitten cuffs can be folded either way.
Sizes starting from 6 months and up to 24, are designed with regular inside stitching. And have the anti-slip feet grip instead.
