Wow! I wish I could lose 70 pounds! I congratulate you on the weight loss! I wouldn't mind being down to an A cup!
One thing I've observed over the last year is the fashion trend toward showing too much cleavage (my opinion) in everyday wear. I see it at the middle school where I teach, with many students (young girls!) as well as a few teachers. I'm not a prude by any stretch of the imagination, but I think it's inappropriate. I think this trend also puts unnecessary pressure on those who lack the cleavage.
Try not to dwell on this thing with yoru breast size. You should be proud of your weight loss. I hope your fiance appreciates it too!
