Unless you're unfortunate enough to have a dress code and have to wear shirts that aren't really long enough to stay tucked in.
I finally found some shirts that match code here at walmart of all places, they have George brand tall shirts that
generally stay tucked in for me in the back. Not always, but close to 100% of the time.
On Fridays however, we have to wear a specific different company-provided shirt, and sadly that one is
not tall by any means, and so I have to retuck it in all day long. So on Friday I can't bend over with anyone behind me because it's guaranteed to pop out and reveal an inch or two of diaper in back.
