I do have some favorite workwear brands that Nordstrom carries, like Chelsea 28 for blouses and wide leg trousers. Another brand that does not get much credit but that does have good staples is Eileen Fisher, who has a great casual, long cardigan, and a slim ankle pant. Sometimes these ankle pants are a good option for casual office days, but many like J.Crew's Minnie Pant and the Banana Republic Sloan can be way too spandexy and tight for the office. Many women end up looking like they're wrapped up in a sausage casing when they wear them, so, to avoid that, try something with a more relaxed fit.
The Best Sheath Dress for Work: is not too tight, hits on or below the knee, and preferably has a higher (modest) neckline. My pick is this dress by Lafayette 148. It has a traditional silhouette and is so classic. The addition of the contrasting piping is perfect.
The Perfect Pencil Skirt For Work: Nordstrom carries Anne Klein, Tahari and Ellen Tracy - basically all workwear masters. AK makes the Suit Pencil Skirt which pairs with this blazer. The quality is good, it's lightweight fabric despite the material, it's lined, and not too fitted through the hips. It also has pintucking in the back, parallel to the zipper, which makes for a great fit. I also like this pencil skirt by Ellen Tracy because the slit is off to the side, and isn't too high. A reasonably priced option can be found here, by Halogen.
I also manage a workwear page on Google+ and would love it if you joined and contributed by posting your chic office style!
