It is common to use a full set of clothing, including underwear, socks or stockings, and sometime even shoes if so desired.  Basically, we need everything your loved one would normally wear in life.  Clothing does not have to be formal, such as dresses or suits, but should still be respectable in appearance.  It is always best to select clothing that has long sleeves, a higher neckline and opaque (not see-through).
