84:10 A woman may not go out with a sanitary napkin if its purpose is just to protect her clothes. Similarly, she may not go out wearing a sanitary belt to protect her clothes unless it's considered a garment in and of itself. However, if she wears the pad to prevent discomfort to herself, it may be worn outside on Shabbos.
84:11 One may lift his garments slightly in order to keep them from dragging in dirt or mud but he may not lift them up completely (which would be considered carrying - Mishnah Brurah 301:117).
