Well, this has to be the most infuriating video i have seen in a while! she cut's the fabric, and suddenly it's a dress. it appears to have no shoulders, so how this thing even stays on remains a mystery, as it's never explained. Don't bother watching, it's a complete waste of time. Also, that music is well annoying too! Avoid!
I have seen other videos giving same pattern and none of them gives the measurements like this one does. ITs one of the best fitting dresses - with hardly any stitching required.
