Natori tankini top. NWT

I love this print. Some animal mixed in with beautiful pink and fuchsia. Has ruching for tummy control. Fully lined. With light molded cups. Underwire. Tag say 6-B/C. It seems a little narrow around to be a size 6. So I listed it as a 4/6. Check measurements. Armpit to armpit unstretched 13.5 inches #004158
