People don't know how to dress for a high school reunion. The clothing choices at my wife's ran from full-on suit & tie/semi-formal evening wear to jeans & t-shirts. In some cases I suppose the venue would dictate the dress, but this reunion was at the Hilltop Steak House in Saugus, Mass. The function facilities are lovely, but the Hilltop is best known as a place where people come to get the better part of an entire cow served on a large plate with a side of rice pilaf. So, some dress to impress and some dress with an eye toward how much beef fat will be on their shirt at the end of the evening, and whether they're likely to wear that shirt ever again.
Strangely appropriate for the reunion of the Class of 1989, there was a guy who took his fashion cues from Crockett & Tubbs. Had it still been 1989, he would have been stylin'.
