‘Wednesday’ pants

Check out the waistband of the fancy pants I am wearing.  This is stitching on the inside of the pants, of course. (So is it OK to wear Wednesday pants on Monday?).  Stitching the day into the waistband is probably a marketing ploy to get me to buy seven pairs of pants – or at least five, one for each working day of the week.  I actually have four pairs of these pants already.  I like to wear the same types of pants every day to work.
