We don’t do homework here but I would suggest you can analyze it yourself by looking at what is being contrasted between the couple’s apparel and where it came from. That should give you a place to start.

Another suggestion is to bear in mind the context in which the poem appears. It is one of a series of poems based on August Sandler’s photographs of citizens from Germany’s Weimar Republic.

@flutherother I wonder how helpful that superb link will be to the op?
