Depending on the season and the company I am keeping,
I always wear either these colored Fruit of the Loom Boxer Briefs
or these colored Hanes briefs,
with a white Hanes V-neck t-shirt,
or a white Hanes wife-pleaser,
all probably from Target or Walmart, all probably bought on sale.
I doubt that I'd buy Calvin Klein or any designer stuff at this point, not for underwear.
