As usual, I cannot tell you what pattern it was, because I use a tracing that I made some years ago - the labelling is a little lacking in detail and just says straight skirt. It has a split at the back and is really very quick and simple to make up.
With sewing time being at a premium, I have to make pieces that are able to be used on a daily basis, and that also go with other garments I already own or plan to make pretty quickly. But, if you are like me, we all know what happens with sewing plans - they tend to remain just that sometimes!
As the weather gets cooler, it can be worn with a jumper and warm tights.
With shoes or with boots:
And with a padded jacket and scarf when it gets much colder.
