The quality and attention to detail is amazing! The ECC team goes above and beyond on every piece. The fit on Summer Travels is true to size. My daughter is 49lbs and 47 inches tall (She is just now getting into a 6/6x in clothes). We purchased a 6 and it fits perfectly with room to grow. The shorts are slightly loose, but they don’t fall down either. The tie in the back makes it to where she will be able to wear it for years to come.
