Pam, it's OK to whine a little bit. :^) It gets old when you have so many obstacles to overcome to get something to fit like it's supposed to. And you're so right that the petites' section only has a fraction of the stuff of misses'. I always feel like I'm missing out!
Hil, I wear maxi skirts too! I have one on today, in fact. I think this is probably what you were talking about, Angie, as far as not limiting yourself because of your height. I love maxi skirts and don't let the fact that I'm short stop me from wearing them. I get them hemmed so that they hit right at the tops of my shoes, and then I try to find a top that I can wear untucked to lengthen the appearance of my torso so as to get better proportions. I know that conventional wisdom says to wear high heels, but I have such a short torso that when I wear maxis, I find that flats or very low heels work better so as not to lengthen my bottom half, which is already long enough. So I have found ways to make a look work when I really want to!
Angie, I did try on some of the brands you mentioned, since I was at Nordie's today. I tried Theory, Maje, and Sandro. The bottoms look like they will work fine in these brands except for the length, which just needs hemming. I tried on a few Theory tops, and they still seem a *bit* big in the armholes and shoulders--but close enough that it is worth trying the more closely fitted pieces on a case-by-case basis. I tried a dress in the Sandro brand, and the waist placement is still too low, unfortunately. And I actually came home with a tunic sweater from Express! It fit very well in the shoulder area. :^)
I plan to try the various stores you mentioned bit by bit over the next several weeks, just stopping in and trying on whatever is in my size, to get an idea of the sizing. I will probably not make purchases yet. I view it as up-front homework. :^)
