When my mum died,we were asked if we wanted her dressed in anything special . As we didnt, she was dressed in a lovely white robe with lace around her neck. There are some big companies who employ people just to "make-up" the deceased.
anyone whos died in our family has been dressed in say a suit or particular item of clothing. from experience if someone dies in hospital or a nursing home we usually wash the person and put clean nightclothes on them while waiting on undertaker. other than that im not quite sure.
