Higher necked vest tops

[watermeloncougar]

I'm looking for vest tops with a higher neckline to wear under summer dresses. I don't mean really high necked, just higher than most vest tops seem to be. I want something that doesn't show cleavage. Any suggestions where to buy?

This?

Or this one, which is 95% cotton?

Cropped and regular length. Cropped are useful for layering, less warm.
