What happened was that she had made the dress for herself, but it didn't fit her well. She offered it to me for Amanda, and commented that it should fit Amanda fine because they both have broad shoulders.
So I brought the dress home, and it fit Amanda great! To top things off, it looked really good on her. Now, this is the same co-worker who kindly made me a diaper bag for our soon-to-be-born first child (unbelievably, the countdown is at 24 days).
So, the short version of the above is that I have an awesome co-worker!
