My 7 year old daughter wears a size 7 in all of her dresses (Gap 6/7, Abercrombie 7/8, Oshkosh 7) and they either fit perfectly or with little room to grow. I ordered Med (7/8) for her in this top and she swam in it. The adjustable straps were good, but the body itself was HUGE. Size smaller in this top. My daughter is 47 inches, 49 pounds and has a 23 inch chest.
