http://www.eshakti.com/default.aspx This is a most interesting clothing site. I looked up skirts and I could say I wanted mid calf on everything. On most of the dresses I could get 3/4 or elbow sleeves, mid calf . So I think it is definitely worth taking a look at this shop because one can customize the dresses and skirts and tops to fit their level of modesty.
As you can see you can customize a dress to your level of modesty. I find this just great.
