I don't have that dress, but I have their ponte sheath dress in 2 colors (and I'm totally ordering another one because one of mine is summery colors and they now make it in winter colors!). The ponte is excellent - thick, non-clingy, very comfortable.
Are you the one that recommended the boys jeans with iron knees? If so, is this the best deal I'm going to get on them or do they go on bigger sales? I check every so often and never see them on sale.
