I hope not, as I just invested in one this year and plan to wear it to death!
I echo Taylor's comment about making sure that it fits well, especially around the waist - that's where I felt lumpy before. I also like that when I wear my particular white shirt, which is one of the Carissa Rose shirts, it has hook-and-eye closures rather than buttons, which eliminates gaping and bunching that I get from buttons.
I used to struggle with the arms bunching up, but what's helped me is to turn back the cuffs on my shirt to "lock" the outer layer (usually a cardigan, or perhaps a thin sweater) in place so it won't shift around.
