I used the basic Crop Shirt Tutorial to make this. It was a really sheer fabric, so I made one out of cotton too and then sewed it inside the sheer one as a lining. I wanted to cinch it in the waist, so I just made a large pintuck around the waist to make a casing and threaded in some elastic.
My daughter is at school, so I pulled out my new dress form as a model. She wears it w/ this cute belt (my daughter not the dress form).
