An Ask Nomi Question for the Frum and Fashionable

[gnomi]

A friend of lcmlc has a wedding to go to and needs a dress that is tzniusdik (conforming to Jewish modesty standards) as well as fancy. What do I know? I make my own for stuff like that. So I turn to y'all... where (in the Boston area or national chains) would you suggest she shop?

Thanks!
