Just me whining about American clothing sizes, skip if you already feel a bit nauseous.

I will try your suggestion.  I feel like I already know their inventory, but maybe I am fooling myself.  It doesn't hurt to try.  How does one go about getting a personal shopper?

At some of the stores here, there are signs in the stores.  I just googled Macy's personal shopper to see what came up, and Macy's has a link on it's web site with info for the various areas:

For Saks, it wasn't quite the same in terms of search results.  But taking a quick look at the store sites might be the quickest way!

Good luck!
