My leery paisley tolerance is unusually high, and though I kind of like the one on the right, neither of them is in quiet good taste.
The second from left in the top photo is fine, but not to my taste, and the third is a little too "suit-y." The far left is okay, but so seasonal and not that easy to wear. I have no idea what one would pair the far right with, unless one's personal aesthetic was "depressing hotel lobby."
Unbel, I still hold that a navy blazer and gray trousers works in the summer time. I think the combination just appeals to me more strongly on a basic level than it does to you. It's got so much range.
