After you draft your sloper, you sew up a muslin. Tweak it if necessary. Here is my muslin, which I thought turned out great. The only tweaks were for sloping shoulder, taking it out a little at the high hip, and narrowing the shoulder. I'm sure the last two alterations were user error when taking my measurements. I always have to alter for a sloping shoulder.
Here is the back and front of my muslin.
After you get your muslin the way you want it, you can draft your own patterns or use your sloper to alter existing patterns. My first effort was this shirt dress pictured below. I included a mandarin collar and front and back yoke. I moved the must dart to the top and gathered it to the yoke. I also made gathers at the back yoke. Then, I made it a drawstring. Taking an idea from Hot Patterns, I elasticized the drawstrings for 2/3's length and added fabric ties for the rest.
