Wear suspenders with sweats.
Do so in public.
Make sure the suspenders are some garish color that weren't even popular during the twentieth century.
Wear a "Hooters" teeshirt under the suspenders.
Tighten suspenders enough so sweats ride above your natural waist & cause the legs to highwater.
Wear mismatched socks. One black dress, one white athletic.
Wear shoes with ducttape.
Shop with woman, presumably wife, who dresses nicely.
Don't comb your hair for a week.
In case you didn't realize, one customer today violated every one of these.
