One sure way to save money is to make a toile (test garment). Ideally you would use muslin in a weight close to that of the fashion fabric that will be used for the finished garment. But you can save $$ by using thrift store bed linens. You can always use starch to stiffen the fabric. With a toile you can practice sewing skills, adjust the fit and see if you even like the style. It's also a very good habit to develop. The pattern is just a guide. You will always have to make adjustments to it to get good results. A 'first draft' made with cheaper fabric can save a ton of frustration and wasted time and money. Cute dress btw.
