Hi SF --
My impressions --
#2 is a no-brainer. The colors read as "True Summer" to me but a) the overall impression is very light thanks to the white parts (which echo the tones in your hair) and b) I actually think you look great in that level of contrast.
#1 I like (minority!) but the rope belt does take it into juniors territory for me seems at odds with your usual casual preferences. Maybe a highly textured belt in one of your key neutrals or fav color-colors? Agree it'd be fun to wear as a tunic, too.
#3 looks a little prim, as fuller-skirted midis often do these days when they don't show upper chest (and I say that as someone who loves the swish of a full midi!). I can see why you were drawn to it.
For daytime I might try to add some light but dangly earrings or something that's a bit fun. I might also try a very narrow belt to make that area between bodice and skirt look a bit more "grown up" and set off your slender waist.
