Hahaha, yes. If I go into stores made for older men who wear suits, their dress shirts are made with the elongated fronts and backs, and have to be tucked in.
If I instead go into stores made for men in their 20s and 30s, and look at dress shirts made to go with slacks and jeans, then they are made to not tuck in.
EDIT: In any case, there are dress shirts available for more formal occasions and employment, which do not require tucking in.
