When I was younger, I found scarves to be rather frumpy. Now I love them, and in some cases I think they make me look more youthful. I find that kind of funny, now that I think about it.
I love scarves because it doesn't matter if you gain or lose weight, or get older, or if clothing styles change. Scarves themselves are pretty much timeless. It's one of the few vintage items that I hoard without feeling guilty about it. I have quite a few that were passed on to me from my mother, her sister, and various other relatives that were cleaning their closets.
I don't always wear them around my neck or shoulders. I sometimes use them as belts, wrap larger ones around my hips, tie them to the handle of my bag for a little flair, wrap them around hat brims to change up the look of the hat, or thread them through a ponytail holder and then around my ponytail and tied in a bow. It's a little bit Sandra Dee to do that, I guess, but I like it. One thing I haven't mastered is wearing them on my head, either as a covering or as a headband. They always slip.
In addition to the silky vintage scarves and the wooly warm winter ones (some of which were hand knit by a friend), I've also stocked up on a bunch of pashmina type scarves in as many colors and patterns as I can find. I keep a few at work to wrap up in when the room is too cold for me. And they make great wraps over bare shouldered outfits when the temperature drops, or I enter an overly air conditioned building.
