I looked in all of our major department stores for the correct size and could not find it.  Found it on Amazon.com!  The shirt is very nice in person.  I picked this one in part for the buttons that matched the shirt - I'm not a fan of white buttons on every color of shirt.  The fabric is nice and it washes well.  Haven't had to iron it yet, so I think the wrinkle-free bit is on track.
