I just start cutting. If I get hot I will remove clothing. This year I took off my heavy coat but left everything else on and did not roll up my sleeves. You don't really get that much blood on you and I had my arms in up to my elbows. The hardest part this year was keeping the snow off my glasses wich caused them to fog up severly. I took them off to finish the job. It goes much quicker when you can see. When it was warmer I remember rolling up my sleeves in just a shirt. What I am realy saying is you get the job done and don't really think about how you will do it.
