The flimsy scarf is perfect for that weather we in my family call 'in-betveen,' when a light jacket is just not quite enough. It's also the perfect accessory for the purely hypothetical office that is freezing in summer and freezinger in winter. One where many of the vents are taped over with duct tape or jammed with deli napkins, and you could swear that over by the copier there is a hint of snow in the air.
Here's a cute $12.50 one from Old Navy. Notice that because it is multiple colorful patterns on a single item, I can still wear it despite both my pattern and color phobias. I think that somehow a colorful multi-patterned item paradoxically works to soothe my phobias in much the same way that ritalin calms those with ADHD, despite its being a stimulant. Also it's possible I have had too much diet coke today.
