I purchased this amazing tunic in-store in the plaid pattern, and couldn't be more thrilled with it. i can already see myself overwearing it, because it's so pretty and easy. i typically wear an xs, and sometimes petite styles. the regular small fits very well. i'm sure the xs would have been alright, but i like the way my forearms don't feel constricted where it buttons, and sizing up seemed to help with gaping by the button holes. i love the way this looks with a variety bottoms and shoes. it
