The photo of this Aqua Towncraft suitcase (suitcase for sale from Etsy shop "bamabelle" and featured on the Etsy homepage) makes me want to jump into the 1940's, travel cross-country by train while wearing a smart skirt suit, stockings, a hat and pumps- aqua suitcase in hand (um, and never mind that the suitcase is from the 1950's...)
Oh! Perhaps the outfit I'd wear would look something like this.
