She is definitely jealous of you and your boobs and curves! I've lost 80lbs and STILL fit into a D cup at LaSenza..which I'm told is a smaller make..but I've gone from a 38 to a 34..my bf says he notices a HUGE difference but oh well....they're just not as 'full' as before..oh well! I'm sure you will look fabulous and show that SIL up!

Yeah, I agree probably jealous and she is definitely wrong on what breasts are. Personally, before I moved away from home (22 y o a), I had gone from 155 to 183 in 2 yrs. My boobs stayed the same size. Subsequently, I moved for grad school and I dropped down to 150. Still have the same boob size. Unfortunately, I have the opposite situation of you though. I have always been a barely B cup... 36B at my heaviest, 34 B currently. I want big boobs but no one in my family has them, big or small. Fat does play a role of course as it does anywhere on the body generally (everyone distributes it differently) , but I definitely wouldn't say that the primary cause for big breasts is being a bit overweight. Cherish your big boobs. I would if I had em!

My mother and I were just talking about weight loss and boob size. I was complaining that although I've lost 18 lbs., the girls aren't getting any smaller. My mother lost about the same amount of weight when she was my age, and hers didn't change at all either.

At my lowest adult weight (136 lbs.), I had DD boobs. I have DD boobs now. I had DD boobs when I started this journey at 172 lbs.

I guess I'm just a heart attack waiting to happen!
