[Not a Mezzo]

I've been over all the department stores in the area, and I'm having a lot of trouble finding a dress for pref. I need a knee-length, sleeveless-yet-not-spaghetti-strap black dress. Something simple, classy, and preferably not like the $149 version I saw at Ann Taylor. Unfortunately, that's also the most like what I need. Any ideas, or should I just keep combing the mall? Thanks, ladies!!
