HI LIz - a very good source of practical, well made classic, mid -lower calf length dresses is Works of the Heart (out of Texas) They are a home based business national in scope. I have used them for 5 years and for myself as well. You can pick out fabric from their choices and create alterations for almost any of their styles, however for girls, you likely won't need any. They are reputable and ethical in their operations. Another similar company that I use is LIllies of the field out of Kansas. They also are quality, and reputable and have a good mix of styles and fabrics. You will likely have to order longer length, but they accommodate such basic alterations easily. Both companies have very reasonable prices for custom made clothes and are fine for girls and women. There are a few other such companies, but these two are consistently excellent. C.
