I've been lusting after the Nina bag by Gabriela Hearst for quite a while now, finally got this medium size one for my birthday. It is dark green leather with rose gold hardware. I've been wearing it with most of my outfits, they are super cute with big coats and knit wear.
While you can find Gabriela Hearst clothing all over the internet and many of them go on sale, but her bags are in very high demand. The only way to shop for one is pre-order through official Gabriela Hearst website by filling out an online form of the specific style and color you want. They are very quick in response. If it is a pre-order item, you will need to put down a deposit.
