You're right about the clothes being frumpy Sarah. I only like clothes by brands I already know like Michael Kors and Sweet Pea, but gosh, look at this: http://www.symplithebest.com/spring/springpage.htm
OK, the black dress on the first page is cute enough, but the rest is awful. That's one of the brands they sell.
Angie recommended square neck tops in another thread for women with broad shoulders. Maybe try those.
I have been experimenting with Myshape by putting in different measurements, and it seems even if my shoulders and hips were 32" (which is unbelievably small), and my chest was a 32AA, but the rest remained the same, I would STILL be an M. Uh, no.
