chambray revisited.

Apparently my love affair with chambray shirts has continued.  I spotted this shirt last week at F21, but didn't end up buying it.  Now I'm kinda wishing I had.  I already own 3 chambray shirts, but this one with it's polka dots is totally different.  Right?!?  Trying to convince myself, cause it's so dang cute that I really think it should be mine.
