I don't understand the negativity about this shirt. No, it's not flannel; it doesn't claim to be. It says it is 95% polyester and 5% spandex, which I hope is true. Polyester is a durable fabric and usually wears like iron; spandex provides "give" so that the shirt moves with you. Yes it is thin. That is a plus for me since it won't be too hot to wear on warmer days. It is also flattering to the figure because it is not designed like a box but actually accentuates female curves, also a plus. The versatility of the sleeve length provides an additional positive element. I ordered 3 of them in different colors and have worn 2 of them so far. I hope they provide years of service because I very much like the way they look on. So far, a winner.
I have very sensitive skin so I don't really like buying online. However, I as very happy with this shirt. Super soft, not very thick so you're not sweating, and the sides taper in so it gives you a waist.
Shirt is super cute and fits true to size.
