Wow, just saw this thread now. HOT topic!
I hadn't ever really thought of hating or loving tunics. My issue with tunics is that since I am short with narrow shoulders, they often overwhelm me. The shoulders are too big, which makes it look sloppy, and then the length is too long or hitting at an unflattering point. As usual, the petite offerings are underwhelming, so I do without.
I do, however, have a sweater dress that I wear with leggings or jeans that seems to match Angie's definition of tunic. I also have a strappy tank that seems to meet the definition as well (it's much longer on me than on the model). I love both these pieces, and it is just occurring to me that I think the love comes from the silhouette being different from what I am used to. This is important information for me, since I am refreshing my wardrobe right now and am feeling like new silhouettes are important for me.
