Tee shirts are tricky to wear, and so are stripes. Choose a too-thin fabric and every bump and bulge is highlighted---too thick and you may as well wear a sweater. Then there are stripes. I don't think they make you look as wide as fashion stylists would have you think, but some patterns are just...loud.
I really like this Land's End striped shirt. The style is chic, the cut is meant for women and best of all...it's on sale!
