In 2000, I bought three similar tall bearded irises: ‘Alizes’, ‘Strictly Ballroom‘, and ‘Altruist‘. The ‘Alizes’ were $6.00 each (actually $3.00 with Schreiner’s discount factored in). One characteristic that distinguishes ‘Alizes’ is the full, cupped shape of its brilliant white standards. (Warning: the Schreiner’s photo shows an unreal shade of bright blue, which it isn’t. ‘Alizes’ is a deep blue tending toward violet.)
