I needed an inexpensive, comfortable undershirt for work. I am a girl and most tank tops that would fit under my shirt are too low cut. I decided to get these shirts instead! They are a great fit! They are inexpensive too, which is nice. The four pack makes it so I don't have to wash them as often. I got these shirts in a medium and they are snug without being restricting. They hit me right at the hip, which is perfect for tucking them in. They don't bag under my clothes because the fit is nice and snug. There is no tag in the back to irritate my skin! Overall, these are perfect! :D
