Every spring, I usually try to find a few shirts that are not t-shirts neccesarily, but are short sleeved and casual and slightly dressier than your average t-shirt. This week I can dress them down with jeans and flats and dress them up with heels to go out. I found this cute t-shirt with birds on it from Lefties for just 13 euros. There is a small zipper pocket on the front and a zipper in the back by the neckline. I think zippers modernize an otherwise classic or even boring shirt, so I really like them.
