Thank you so much for your responses. Seems like most folks think I should keep the dress. (This will be my very, very first time wearing a dress. Excited!) Also thanks for the encouragement. I'm actually looking forward to the reunion.
Everyone seems to hate the boots. Heels are out of the question (I'm tall enough and awkward enough as it is). And size-12 girls can't just pop out to the discount store and pick out whatever they fancy. Occasionally I'll fall in love with something, but otherwise, barring an Internet order, I'm stuck with what's in my closet. I've gotten a lot of compliments on those ankle boots, but the people have spoken. The alternative is a pair of ballet-style flats I bought when I was first going out as Suzi, so I'll probably go with them.
