I used flannel fabric, it was on clearance. I took an old bathing suit top that fit and pinned it to my fabric. I then gave the triangles darts and finished the edges. I wanted a flintstone look with this so be as messy as possible. When I made the straps I did them super long so i could try it on and cut later. I added cups and zippers last, that was pretty much it. Let me know if you have any questions. . .
