The excitation energy systematics of $\ensuremath{\pi}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}{h}_{11/2}$ yrast bands of odd-odd isotopes ${}^{118--132}\mathrm{Cs}$ are studied, and as a result of this study we suggest that the spin values of lowest observed states of yrast bands of ${}^{118,122,124,126,128}\mathrm{Cs}$ be reassigned as 8, 9, 9, 9, and 10, respectively. These new spin assignments are also supported by the argument of alignment additivity.
