I bought two of these tights, 10-14 and 6-8 because the reviews said the tights were too small. My daughter is 6 years old and wears a size 7/8 and is about 3ft 10 inches taller and taller than most kids her age. 55 pounds 10-14 was too big for the legs; too limp. 6-8 fits perfectly. Order the size your child wears.
