Thank you all for the recommendations! One of the big challenges of where we live is that even though I live in a town often associated with posh shopping, there's actually not that many shopping options, and I'm loathe to drive an hour-plus to better shopping. So I really don't have many opportunities to try different clothing brands. And because my body type doesn't fit the "style" associated with SoCal, I'm even more limited (tall sizes are nearly nonexistent here, believe it or not).
We do have a Talbot's and a WHBM, so I'll start there.
JC Penney, Express and Ann Taylor are all an hour away, so maybe the next time I'm up for a big shopping run, I'll try them.
Thanks again (and, if there are more out there -- definitely keep them coming!)
