fern, yes, I do have some great fabric sources. Both of those fabrics you noted are from http://www.marcytilton.com. I love her selection. It can be hard to gauge color on her site, though I've found them pretty true to life. I have a Pantone shopping guide that I use to select fabrics at emmaonesock.com, where she gives the color codes. I use a lot of patterns from The Sewing Workshop, which has a great selection of fabric, too. I also have some great local fabric stores: Nancy's Sewing Basket and Pacific Fabrics.
unfrumped, thank you for chiming in. I love your oxford looks, and it's really helpful to have your input here. I feel you hit on all the issues I have. Your point about not liking a look even though it may be on trend is a good one--I feel like this look is either okay or almost there, but it's not yet what I want. And like you, I love the idea of oxfords for comfort, especially for wearing to work. To be honest, these oxfords are comfy but not be-all, end-all comfy, so I've been thinking I need to replace them, anyway. (And these were replacements for some Nayas I got last year at NAS, which turned out to be too narrow!)
shevia, I liked the look better in the mirror than in the photos. So I do think the detail on the shoes and the taper of the shoe is more evident IRL.
Suz, great idea about the scrunch. Something I don't think about enough--I usually scrunch for comfort, rather than actually thinking about how it looks--ha ha! And the low-waisted pants are a good observation, too. I am SO high-waisted in actuality, it's almost comical.
