The dress issue has been resolved. Turns out I had a dress all along!
I was whining about finding a dress, hating shopping, etc. when J asked me to show him the dresses that I have. I started pulling things out of the closet, and found a pretty red dress that I bought at a consignment shop a couple of years ago (anticipating the red dress party, which I've never attended) and have never worn. I had dismissed this dress as an option as it is BRIGHT RED, a color I rarely wear. J asked me to try it on. I obliged. It's cute. It is actually cuter on me now than when I bought it. AND the top is breastfeeding-friendly. Did I mention it's cute?
That settled it. I'm wearing the red dress. But shoes? Accessories?
Found a pair of shiny black ballet flats at the store for more than 50% off, meeting my cheapskatey needs. I made a necklace and pair of earrings from beads I already had in my bead stash, probably totaling $6 with all the materials. Woohoo!
J is currently out shopping for a red tie that will look good with my dress without making him look like an MP (Member of Parliament - a Brit or Canadian politician). Besides, he could probably use a new tie anyhow.
Wardrobe issues solved. Now we just need to bake, clean and pack for the wedding followed by camping and climbing followed by Thanksgiving festivities. Hooray!
