Those wide legged pants look mighty good on you. My fave is number two, simply because of the head to toe seamless column of blue. Polished, elegant. I wouldn't tuck that one as it would interrupt that flow. The third one--might try untying it at the top for a more relaxed look. The eye would then not stop at that knot at the neck. The first one is a watercolor dream, a very sweet top. For me, that first fold/waterfall would hit me where I need less emphasis but it does not on you. A nice complement of colors in that top, a Monet-dream.
