They seem to be everywhere. So my question is when is it practical to buy one in terms of
1. colors they work with-- could you use it with your whole wardrobe or is its use going to be limited to certain color schemes?
2. could you use it year round i.e. in spring and summer too?
3. is this a trend that's just going to go away?
I'm really attracted to a few but I'm afraid with my mostly cool colored wardrobe I'd be better off with warm colored handbags.
