All the men coming for the Alibi Club should bring options of the items mentioned below in the original posting for Wed 6/15. You will find this post by scrolling down after you read this. Yet should also bring things that would still be fitting to the character yet slightly more casual. These things would include:
Navy blazer w gold buttons
Thin dress pullover sweaters
L/S Button shirts that could be worn without a jacket
The season is late winter early spring so more muted colors will be best.
All still very much men of wealth and influence, but more perhaps as they would be seen at a country club.
Again, bring all of the items listed in the posting below, the suits shirts and ties first mentioned and then some options of these less dressy options.
