Okay reporting back. Thanks for the prodding, everyone, to go through the closet again. I didn't find anything that I didn't know about, but I did discover that I could fit into the suit with the skirt again! That's a major plus; it gives me a skirt and a jacket, and I have started building a capsule wardrobe for the trip around it. It's purple, a little too dark to fit the season's pastels, but is distinctive enough to qualify as a signature piece. It'll do nicely. Plus, I have not one but four scarves that will coordinate well with it, and scarves are a breeze to pack.
I have two good white blouses, either of which would do nicely as another piece of the capsule, but they each have a stain. I'm going to get some Oxy cleaner and soak the stains to see if I can salvage one or the other.
I was able to repair the go-to black silk sweater, so I'm set there.
One of the new shirts I've recently bought is a nice shirt/jacket in gray that coordinates with the purple and with the black-and-white that I'm going to make the basis for everything else. I have a good black shell, and I need to find a white shell.
I will also still have to buy the black pants and the loafers. I have a dressy pair of Danskos that will go with the skirt (yay for shoe repair, which they've had twice).
Hadlily, I don't think anyone will drum you out of the club, but don't give up on used and consignment. Most of my wardrobe is (was, for the worn out parts) Ann Taylor, Talbots, and Jones New York, and I didn't buy any of it new. That's one reason I'm looking so hard now and making decisions more than a month ahead of time: to have the time to look in thrift stores. I'll give the pants another two to three weeks to turn up at s thrift store before I break down and go to the outlets. The white shell I'm certain I can find at a thrift store, and I'm not much worried about brand for a shell. The shoes, because of my arch support issues, I'll probably buy new, but I do fine in loafers from Dr Scholls with an added arch support insert. Sandals are harder because I can't add the insert. I usually wear Dansko or Ecco; I'll have a look at Mephisto. I may get the sandals this year, but we'll see.
One of my goals with any business trip is to pack only a small carryon bag and a laptop bag. It makes life so much easier and airports much more bearable. I think I'll be able to pull it off with this capsule wardrobe -- I'll travel in the suit, probably, but the hotel room has iron and ironing board, and I'm not afraid of them.
Now. Can I manage with only an iPad, I wonder, or do I need to schlep a laptop?
