“My baby girl is 3mo old and about 12 pounds 23.5in long! This suit is adorable and such great quality! I bought the periwinkle and it is adorable with the ruffles. It fits snug around her body and a little loose in the arms- perfect and comfy for moving around in. I will be buying the next size up as well since she will grow out of it before we know it. Great product”
