The primary criteria upon which one must based their decision on what to wear is the water temperature. As a general guideline, the 100 degree rule can be used. When the water temperature plus the air temperature is less than 100 degrees, a wet suit or dry suit (with a warm undergarment) should be warn. This is only a guideline; when in doubt dress for the water temperature.

Clothes made of cotton should not be worn as cotton retains water. Instead wool, fleece, or some other moisture wicking material should be worn to provide warmth.

Some sort of foot protection should always be worn. This does not include sandels such as Teva's as the straps can easily get caught on footpegs or rigging. Shoes will not only proved warmth in cold water but will protect the feet when entering and exiting on land as well as provide protection from glass or other sharp objects in the water.

When paddling in extreme cold conditions, appropriate attire should include a wet suit or dry suit, shoes, neoprene gloves, and a neoprene or fleece lined hat.

At the other extreme, when paddling on a sunny day, a large hat and long sleeves should be worn as well as sunscreen as protection from sunburn. It's probably not a bad idea to carry along some bug repellant as well. Don't forget to bring extra water.
