Mazkwok has published this free sewing pattern that is “More than a Classic Straight Skirt”. Here’s how they describe it:
A straight skirt is just so easy and simple to pair with, it makes you look both neat and never out of style. In fact, straight skirt is the type of bottoms give your legs a bit more length. With just basic sewing skill, drafting a pattern for your own size is not such a task, a classic one is easy peasy anyway.
