John,
As far as the blazers you'll recognize them as the ones you've seen at all the different annual meetings and gatherings (well not this past year...) for the past few years.
Here's President, Olwen Huxley dedicating boats
Here's the 2018 Henley Masters E4+ note that Tom Kiernan (second from right) is wearing an older version
Here's Stu Sloan, talking to a slightly shorter man, in Henley-on-Thames
Here are Aaron Moburg-Jones and Michael Cunningham, enjoying some oysters at a previous annual meeting
Inside the lining is your name and monogram, and note also the two stripes and three stars on the cuff - a stylistic homage to the DC flag.
As far as the other apparel, if you've seen me leaving the club in the morning after rowing basically any weekday in the past 7 years... a number of other members have gotten non-PBC blazer apparel, mostly suits and shirts, and they're welcome to chime in with their recommendations.
