For a tunic, this shirt is cute and flattering, not just a boxy shirt like so many tunics are.  It has different buttons down the front and an unobtrusive ruffle at the bottom that even a 50-something woman can tolerate without looking inappropriately young.  I'm 54 years old, 5'8", apple body type, and bought this shirt in a size Large in black.  It's flattering for my body type, gives me a little more of a waistline than I really have and covers my hips/bum.  I'm thinking of buying it in another color as well.

The fabric is a sturdy stretch cotton - very comfortable.  It looks nice with a pair of jeans, a pair of white pants, or even leggings.
