Saint Margaret of Antioch
I have included a selection of paintings of St. Margaret and in none of them does she have a hair out of place, let alone blood on her dress. Below is Raphael's version from around 1518. Supposedly she has just survived being eaten alive by Satan in the form of a dragon, yet she has emerged unscathed. She was revered after this as the patron saint of childbirth and pregnant women.
St. Margaret of Antioch is known as St. Marina in the Eastern Orthodox church. Some more backstory here.
