It means that it is really not flattering- If you think about what a potato sack looks like, its just loose and has no shape to it at all. Its just a bag that brushes over the curves of a body. So it is not flattering.
Another word for the coarse sack is a "gunnysack" or "potato sack."

The potato sack race involves hopping. Contestants step into a potato sack and pull it up with their hands. With both feet in the sack, they are obliged, on the signal, to get from the start to the finish before others. Running is not possible, and walking is difficult in the extreme because the space in the sack is very limited. That leaves contestants hopping the length of the course, as this is the fastest way to move under the conditions.
