For Christmas I wanted to get my mother a shirt like one I have that I know she likes a lot. (http://www.jcrew.com/womens_ca...../44875.jsp)
The problem is I know that button-down shirts are problematic for her due to her bust size. I think she wears a 36DD. She is 5'4" and about 150 pounds, hourglass figure. I was thinking to order this shirt in a 12, which is supposed to fit a bust of 39 inches, or perhaps a petite size 14, which should be comparable in the bust. Perhaps though I just shouldn't even try with the button-down shirt since if it doesn't work out, I know it is a bit frustrating to her.

Does anyone have an opinion on the sizing or whether it's just a bad idea?
