The button down White Shirt is considered the most versatile and important element in a guy's wardrobe. It goes with nearly everything. With suits, you're a lawyer or getting married; with black pants, you're a financial adviser or going for a wedding dinner (the common perception in Singapore anyway); with a pair of jeans or khakis, you become smart casual; with an otherwise bare woman, well you get hot under the collar (this is an international phenomenon). There's probably just one thing that don't really fit the white shirt - the white pants (I'm sure you can figure this one out yourself).
Catmasutra cat in the empty pocket was motivation enough. This is the Catmasutra white shirt in its "after" state, and not the well-pressed, seemingly immaculate one. Pure white, from another perspective, is simply the absence of color.
