It’s hard to come by a reasonably priced leather skirt. They either look cheap, or the fabric is too waxed (aka made to look like more expensive leather) that they all turn out to be disappointments. I think I’ve managed to find a selection of skirts that look high-end, but are a bit more affordable.
Below, on the left, we find two high-end leather skirts followed by their more reasonably priced equivalents on the right.
