At Chico's I'd recommend black slacks with a jacket like this and a tank with bit of color.
At Talbots, I'd recommend something like this. It's not black, but it's sharp and isn't too old looking.
Hey...that's not a bad rundown.
I guess I could at least look quickly at Penney's. I didn't look at anything other than one piece dresses and clearance dress sets. And it's close.
Likely I'll wimp out and go the cheap route, though. That...and honestly, I've never really owned anything seriesly dressy.
