I've scarce on the forum recently, so I don't know your style as well as some of the others. I'd like to chime in with this:
1. The gingham top would look great over last years denim shorts. Gingham might be a bit "out there" for your style, but it is very on trend, and, as is it here, also a graphic statement, which might suit you well.
2. I'm left with the sense that the long sheer tunic and the kimono are the right idea, in the wrong colors and prints for you. I think there's definitely a version of these garments for you, however. I just purchased two shorter kimono tops for my summer wardrobe, and have one long, sheet tunic I'm considering. Mine are floral, but you might want to try one with a bolder, more graphic print, or in a rich solid. I've attached on of my new tops below.
