Fall means breaking out your corduroy clothes and receiving joy in feeling how frickin' soft that stuff is. I paired my corduroy pants with a warm cardigan and a tank top because mother nature can never make up her mind about the weather. I'm freezing in the morning and sweating by mid-day. If you switch out the cardigan for a blazer or switch out the cardigan and tank for a blouse, you would have a business casual look ready to go.
If it's cold out, you could swap the heels for some combat or knee-high boots and throw on a coat. So many possibilities.
Make good choices,
