Hee, those things were the biggest pain in the neck I've ever run into. Literally. The wings strapped on with elastic over the shoulders, but there were also a couple of long laces that we couldn't quite figure out what to do with them. We tried tying them a couple of different ways, but none of them seemed to help with the fact that the damn wings kept bopping me in the back of the head. To make matters worse, the first time I tried them on, one of the elastic bands snapped on one end. Fortunately, Zach had safety pins (I think he owns stock, he must go through tons for his Halloween costumes) and we were able to pin the broken band. Fortunately, that was at J & Z's apartment before we went off to the party.
The second night, I carried the wings to the bar with me and, of course, as soon as I put them on the other end of the elastic band breaks. Oh, no! My wings had been plucked! I considered, for a while, announcing myself as a street walker. However, the intrepid Juliana called up the even more intrepid Zach and he brought the magic pins with him, again. All I can say is, being a social butterfly is much harder than it appears.
