Interesting 2002 study University of Tennessee forensic “Body Farm” analysis of cadavers with clothing on compared to nude and effects on decomposition. So the need for anthropologist exam of remains for help with time of death. This study has pictures ( be prepared) taking into account all IV stages of decomposition. If you don’t have the time look at beginning introduction portion and conclusion. I could summarize IMO, but I know lots of experts here and I’m more interested in any thoughts and ideas you have relating to this area.

Some interesting findings : It was determined that clothing retards the process of decomposition in the spring and summer.
A clothed body takes approximately 1.7 times longer in the spring and twice as long in the summer to decompose than a nude cadaver.
In the conclusion portion of study
Two notable exceptions are rape and homicide victims, and homeless individuals. Victims of rape and homicide are often thrown out nude, or with little clothing. Homeless individuals are known to dress in multiple layers throughout the year, making a season estimate difficult. In such a case, it is assumed that multiple layers would further curtail the decomposition process.
