Oddly, I find myself alone, but I think #3 is just okay. I think it looks fine (better than most people on a very good day for them). But Una caliber? Not sure. I think it is the fact that it is so very low contrast. Dark hair, tanned skin, dark grey, black. Then neon. I feel like you are missing a slightly lighter color in there to give it more liveliness. Or I'd go with a black tank and get the whole column of non-color thing plus neon.
Love the Uniqlo tee--tell me more about it! And Kona, sweet Kona! What a cutie. Big behind the ear scratch for Kona, please!
