I have some pants that tend to "whisker" more than others. They don't fit tighter than others but probably just the fabric. Once whiskered, I don't know of an alternative other than to take them to the dry cleaners (for the dry clean only fabrics). This is frustrating for me when the whiskers happen after only one wear. While I like to keep my clothes clean, I typically wear a pair of trousers about 3 times before laundering.

Does anyone have practical solutions for eliminating or reducing whiskers on what I already own and things to look out for in new trousers I buy in the future?
