My husbands suits have that same little film of dust on the shoulders. I haven't had to buy dressy clothes for a while now. I have a few casual skirts etc that I wear to work, but it's mostly slacks I wear to the office anyways. I now hate to wear pantyhose!! (Not that I ever really liked to but before I didn't have a choice.) My mom - a faithful JW has recently stopped buying a new outfit for all the normal JW occasions - Memorial, DA,CA, SAD etc. She says why bother anymore? Good for her! She has more clothes than I could ever wear in two years.
