Are we allowed to roll up our sleeves if we wear long-sleeved shirts or is that technically not FOM approved. I think a rolled up sleeve conveys a professionally-sophisticated, yet approachable demeanor.

Also does the rolling up of the sleeve have any effect on the being a tool? And if so, how far up ones arm would the sleeve need to be rolled up to so as to disqualify someone as being a tool? Forearm? Elbow? Lower Bicep?
