Long sleeved shirts.
Not only a good idea but also a Boeing recommendation...
*******************************
Boeing recommended to use, or not use, long sleeve shirts?
Do you have a reference?

From a recent [aug 23 2007] Boeing bulletin about landing on slippery runways (and I'm sure it is in more of their publications):
Reverse Thrust Operation
Awareness of the position of the forward and reverse thrust levers must be maintained
during the landing phase. Improper seat position as well as the wearing of long jacket or
shirt sleeves may cause inadvertent advancement of the forward thrust levers, preventing
movement of the reverse thrust levers.
