Pancharatra Pradipa also gives the following guide to cloth: Unclean and Improper Cloth (PP 1.7 vastra paridhanam) A devotee should not wear dirty cloth, especially when cooking or worshiping the Deity. Used cloth that has not been washed and dried again is considered unclean. Cloth worn while sleeping, passing urine or stool, or having sex is unclean. Cloth that touches anything impure, such as wine, meat, blood, a dead body, or a woman in her menstrual period, is also contaminated. Cloth washed by a public laundry service and cloth that, though washed, has become stale are also unclean and therefore unfit to wear during Deity worship. While worshiping the Deity, you should not wear the following types of cloth: brightly-colored cloth (for men), damp cloth, cloth that is too long or too short to be worn properly, stitched or sewn cloth (for men), torn cloth, oil- or dirt-stained cloth, soiled cloth, burnt cloth, or cloth chewed by animals or insects. However, you may wear silk many times before washing it, provided it has not contacted anything impure or been worn in impure places. Unbleached, raw matkA (ahiMsa) silk is the best for pUjA. Sheep's wool is said to be always pure, but still, you should not wear ordinary woolen cloth when worshiping the Deity, because wool particles may fall on the Deity's paraphernalia. However, you may wear wool cloth if it is very fine, "nonshedding" wool, in which case you should reserve these items only for pUjA. Synthetic cloth should not be worn when worshiping the Deity.

This is a guideline, not invented by me.
If you feel some portion of it is unreasonable, please do not follow that.
