I have been looking for a plain white tee that is thick enough not to show black or nude bras. I am a size 5/6, 5'6" tall, weighs 130lbs and the medium sized fit just right after I washed the tee and it shrunk to a smaller fit. Yes, the tee shirt that I thought was too big at first (when new) shrunk after a full cycle on my dryer. The material is stretchy enough to accomodate fitted look and long enough not to show my belly when I raise my arms up.  I WISHED the V neck could have been deeper though coz it has the round neck effect.  Great for casual pants and blazer days. It also looks better when ironed.
