I really like the looks of #2 and #3. Do you have time to buy, take home, try with different accessories etc. and return if necessary?
Like you, I also like #1 and #4, but I once heard Angie mentioning something about borders on hemlines (a long time ago, in reference to a wrap dress I was considering) in that they can sometimes chop up the leg line. Not sure these two have an actual border in the same way as the wrap dress I was considering did (solid black border in that case), but still - seeing the borders across the neckline and the leg line gives me pause. That said, I am definitely *not* an expert on these things so take this with a huge grain of salt. Of the two, I like #1 best and can see you in that fab blue with black ....it would look amazing on you. I also like that it has a bit of a 'mod' vibe...yes, it's definitely a contender!
Hmm...not much help, am I? Can you try #1 through #3? As in buy and try at home before deciding?
I'm not certain about the sleeves on #3, but I still love that peplum shape, so if I were you, I'd want to at least try it out.
ETA: I'd put #1 as top contender.
