To stay dry and warm during activities that require you to dress your best and wear your suit coat, you may add layers as needed:

First, layer a suit vest or sweater under your suit coat. (Suit vests may not be worn alone, but only under your suit coat.)

Second, if you are still not warm enough with a sweater or vest, you may add another layer over your suit coat such as an overcoat or raincoat.

Be sure to wear your nametag on the outermost layer of clothing so that others may clearly identify you as a missionary.
