From the Decades of Style blog:
The Baltimore dress is a loose fitting sleeveless frock with paneling at the front hip which allows for color blocking and fun with directional prints. Lighter weight fabrics like silk chiffon or crepe, rayon, voile, handkerchief linen are recommended because of the loose fit and amount of ease in this dress. You can use medium weight cotton, but the drape will be more stiff, especially in the front skirt panel.
