Wardrobe rituals

Every two to three times a year, I find myself in the awkward situation of having to conjure an appropriate outfit for a special occasion. Each time, as I assess my wardrobe of shorts and tees and work clothes and (mostly black based) formal dresses, I resolve to buy clothes that are in-between. And each time I manage to wrangle something, which leads to me concluding that I can still afford to put this strange ritual of procuring clothes on hold. It's getting tougher these days though - I can tell if I'm already thinking about how to allocate appropriate pieces of cloth to events happening in the next month.
