This shirt is so lightweight you hardly notice you have it on even in tropical weather.  It dries quickly overnight and does wrinkle quite a bit but we were in Africa and everyone was wrinkled, so it did not matter.  The fabric is soft and it kept me cool while providing good coverage against bugs and sun.  I wear a size medium but purchased a large to wear over a t-shirt; it is a bit large through the shoulders but smaller in the bust for someone larger on top.  The sleeves are a bit long but you can roll them up easily or just turn up the cuff once.  I chose the tan and green tiny plaid which looks great with tan or brown pants or jeans.  I will enjoy the blouse for years to come.
