I love #1 and #2 (especially #2). For some reason I'm not crazy about #3 but it might be something that's really cute on. I haven't seen any IRL so I'm not much help, sorry.
I have a top that I got today that looks just like number 1/2 by the brand To The Max. I totally agree with Collette about how they tie at a weird spot but it has that slouchy tunic look going on that I like.
