This young woman, dressed to the nines in a man's suit complete with pocket watch, is probably a baby-dyke ready for Girls' Night Out, and saying goodbye to her chihuahua on the porch. That, or she's a mail carrier.
Or! -- as the chihuahua is sitting on a suitcase, the dog could be going with his butch girlfriend on a road trip or train journey. Also on the suitcase is a baton. A baton twirling baby-dyke? A second travel case looks like it holds either a rifle or a musical intrument. Going to a shooting contest, or part of an orchestra parade?
