I love a peplum top. I would wear them all the time if I thought I could get away with it. ;
I love how much you can customize, and size Sewing Cake Patterns.
Not difficult patterns but if you run into issues check out the website where you can find pictures, sew a longs, videos and a community. You can also send a message and get help that way.
Take your measurements and play around with sizes. Since I would use this pattern again and again. I did get blank sheets of pattern paper and made my own pattern pieces. I would even make the top without a peplum as it fits well.
