Land's End makes a gender neutral mesh polo and a gender neutral "super tee" both of which have a pink color option. Their little kids' sizes for boys and girls are the same. No need to spend Lacoste type money! They also have a "buy 3, get $ off" type deal on their knits.
Until grade school peer pressure persuaded him to take it underground, my son's favorite color was pink, and he had a Land's End pink polo every year.
