I need your help! I've enjoyed YLF for about two years, but 2010 was crazy so I lapsed into occasional peeks rather than my previous modest participation.

This Friday I'll be in downtown Seattle for a week -- my dear husband has a conference. In fact, this is the first time I've ever been able to accompany him. While he's busy, I plan to enjoy the core of the great city I grew up in/near (art museum! coffee! vistas! seafood! and a hotel room in which to relax, knit, and read!). I am also excited to check out stores such as Nordstrom, ATL, and H&M that I don't have easy access to here in an Oklahoma college town but that are an easy walk from my hotel at 7th & Pike. So... I'm looking for store recommendations

My style is classic, skirt-wearing, smart casual MOTG nearing 50 and I'm a curvy pear. My budget is usually Target, JCPenneys, and thrifting, but I am willing to spend more than my usual for core items. In fact, I have a short list of needs that I am looking for:
* a couple of pretty, seamed, well-fitting bras (and I need a bra fitting)
* short black half-slip (18"?), preferably silk, for the skirts I wear every day
* micro fishnets
* denim pencil skirt but not 5-pocket styling

Could you give recommendations for stores not to miss in downtown Seattle, whether for my shopping list items, great stores / departments that won't bust my budget, or just 'must-see's? Thank you so much!
