I`ve never seen the ad, but I think light grey is the keyword here. If one was to wear a pinstripe suit jacket as a sports jacket, then light grey would be the color to try. Also, I imagine that the jacket was probably made of a flanel or something similar in taste...not just a regular wool, suit jacket. Charcoal pinstripe suit jacket would look horrible as a sports jacket. As mentioned earlier, the pockets make a big difference too.
