So, I know this seems a bit ridiculous to be wanting a lightweight cotton jacket right now, but hear me out: the fall/spring light jacket-wearing seasons are so short that it just doesn’t make sense to wear a cotton jacket solely for those seasons. What I propose is to get the Fab Casual Jacket , $17.50, and start wearing it now. You can definitely fit a thin cashmere sweater underneath, and it adds an extra chic layer in these terribly frigid temperatures. Choose from six fabulous colors (my three favorites are above!). Add $5.95 for s&h.
