I'm in the market for a couple of interesting button-down shirts for the spring/summer. I especially like unusual shape/feature details but can also go with unique patterns/material.

I'm mostly interested for non-work wear - that is, at home, around town, date nights.

Here are a few that I collected from Zara, plus an Angie pick from Club Monaco. Do you like any of these? Do you know of any others - especially with shorter sleeves? Thanks in advance for your help.
