I began sewing when I was 10, started with a very plain shift dress and over the years have made all manner of clothes and soft furnishings. Skirts are relatively easy, the only fiddly bit is inserting the zip, but if you youtube or pinterest it, there should be lots of videos showing how to do it. I do think though, if you have never sewn anything before, you would be better taking a few classes first, or get a friend to show you the basics. It really isn't difficult once you get going, most of it is common sense. Good luck and happy sewing.
