the blue shirt obsession

Last summer I fell for the blue shirt all over again.  Found myself wanting one, just to mix into my wardrobe, then another.  Next thing I knew, I'd started a mini collection.  Got all three of these, on separate occasions from my neighborhood Goodwill; 5 bucks each.

Can't wait to pull them back out when temperatures warm up. 
What staples are you bringing back next summer? What pieces do you think you'll always have in your wardrobe?
