So I think I am finally ready to take the plunge and order from Naartjie. I heard that their tops and pants run differently. Liza is starting to wear a 6x, Kasey is starting to wear a 4t, and Julia is in 0-3 month right now but I am guessing she will be in 3-6 month by summer. What Naartjie sizes would you recomend for my girls? How do their dresses run? TIA!
