If you have slim, read really skinny, calves how do you wear your ankle boots. Do you wear them with straight leg jeans which I would do without a second thought? Do you wear them with skinnies or with tights/leggings and skirts or dresses? If you do, how slim are your calves? Mine are around 33-34cm per Duo boots widths (!) and I'm not sure I would have the confidence to wear ankle boots with skinnies or dresses.
Thanks
