I started sewing back in the early 60's, after my first home ec class of a pillow or laundry bag I was not interested in pursing as my mother could make beautiful designer clothes. But my Mom encouraged me to find a pattern I thought was cool and fabric I loved. I picked out a navy and white hounds tooth wool and a vogue designer pattern. I followed the directions very carefully and it turned out beautifully. I was able to match all the checks, make a lining, put in a zipper, make a lining and bound button holes. I did ask Mom for help with the bound button holes and she taught me the best way to do fancy hand work. She made me baste all seams( by hand with thread). That is the best advice I ever learned. I learned self confidence! It helps me today to be fearless.
I don't know what kind of directions you will find in the pattern you buy, but if your willing to put in the effort, you will be richly rewarded.
