I bought this item knowing it ran small. I am familiar with the Zenana brand. I bought it to be a snugger layer under my cute tanks. I was having a hard time finding racer back. This tank was perfect for my needs. Im 58, 145 lbs, long torso. A large fits snug and is plenty  long. Would have given5 stars, as perfectly met my needs but wanted others to beware that runs small and is too thin to wear alone.
