We have this thing with display windows — and particularly, the Valley's lack of them. There's something special about a stylishly posed swing dress catching your eye, and the ladies at Antique Sugar know this all too well. Not that we need convincing to step inside the shop. Sugar has been a favorite spot for both men's and women's vintage clothing for years now. The boutique's in a league of its own downtown, with candy-colored party dresses, hefty turquoise-and-silver belt buckles, and the tacky-meets-sparkly overkill of costume jewelry. But still, we really like those windows.
