citygardener, I have asked friends in whom I have confided about my incontinence whether they could tell that I was wearing diapers and, even after knowing my secret, all said "no." Even during the day, I wear a premium diaper like MegaMax, InControl Elite Hybrid, BetterDry, etc, with a booster pad, a cloth toweling pull-up (from Kins), and a diaper cover. I wear black pants and, although that is substantial bulk, no one can tell.

Please see the note below from my draft book on incontinence.
A company that sells excellent pants and shorts for anyone wearing a diaper (or similar product) is the Duluth Trading Company. Known for their durable workwear, the fit of their pants is comfortable and allows enough space for diapers. Their pants are known for what may be the best feature for anyone wearing diapers - a hidden gusset in the crotch to allow extra flexibility of movement. That extra fabric in the crotch provides enough additional space to accommodate, and hide, a premium diaper, with a booster pad. I wear these and find the quality to be excellent. Their products are not inexpensive, but the company has almost constant sales and discounts.
I am sure there must be other clothing manufacturers similarly incorporating a gusset in their pants. Does anyone know of any?
