I love single pleats, and I'd wear more if I could find them OTR in a fit that suits me. For me they have to be inward facing, as is the way I prefer with any pleats. Many of the English brands sell this style, and it's especially popular on Savile Row these days. They look a lot cleaner than double pleats, but they need to fit well or they'll look terrible.
