Image databases can be a great way to research a color palette and you don't have to limit yourself to images corresponding to the period of the costumes. Imagine contemporary costume designs in palettes drawn from these two examples from the 1930-40s: Digital Public Library of America (DPLA) postcards of Palm Springs and Library Library of Congress theater posters created by the California Federal Arts Project.
