Decided to try this sleeveless shirt for my work shirt. I have to wear it under a work smock and the one the company gives us is terrible, unflattering, and material makes you overheat. This shirt is lightweight, soft and comfortable. I am a medium and decided to buy large after comments. Large was a good choice. I have also washed it a couple times already and it holds up in wash, no shrinking or change in material. I went back and bought a second one. Happy with purchase.
