Old Navy Shine On Racetrack Tank size Large L

Old Navy Shine On Racetrack Tank size Large L. Worn twice. In excellent condition. Would work well over a swimsuit lounging by the pool. Super cute shimmery golden graphic of the USA. I cut the bottom tag that was inside of the tank out as it was bothering me. Not sure what material it is. Looks like cotton but isn't must a blend of that and something else.
