In white this is definitely the sort of dress for people who get cabs, or have a driver. Not one you want to wear on the bus or while hanging around the train station, but then, if you can afford to buy expensive dresses you can probably afford a cab.
This feels very 1950s with it’s 3/4 sleeves and straight wiggle style skirt, I can imagine Marilyn pouring herself into it. Just add seamed stockings and red lipstick.
