A question about potential breast development

[Guest Lizzie McTrucker]

As they say, I guess the rule of thumb for your potential breast development is one cup size smaller than the women in your immediate family. However this doesn't specify if that's before or after having children. Both my mom and my sister are a little busty but they both have children so I assume their chest is bigger now than before they were pregnant. I also looked online and I guess breast development varies where the mom and an older daughter may have a large chest but the younger daughter does not.

So does the general rule still apply or is this also a case of YMMV?

[Guest Mayrah]

If thats the case, HELLO B's!

As for answering the actual question, i dont know.

[Guest Joni Hayes]

I've heard from quite a few women in Australia much further down the road then I that

this expect a cup less then your mum/sister is a furphy.

Hey I can give some input on this . Before pregnancy you have normal boobies when you fall pregnant thy grow as the baby develops and after the baby is born my goddess thy are the biggest u will ever see them unbelievable . Then booooooooooo thy shrink sometimes smaller than ur original size before pregnancy . Have to share a funny story . Here in Australia after a women has given birth to help with the massive build up of nutrition for the baby thy encourage you to put cold garbage leaves to bring them down . I nearly laughed but bearing the pain of feeling like thy were going to explode I gave it a go .thy worked Hehehehehe my room smelt like spring rolls its like I had my own Chinese restaurant in there . My partner would come to visit us and I would do my hair and clean myself up to look all pretty forgetting every time that I smelt like a fresh cooked spring roll ;/ and as for genetics my two girls are bigger than me :/

[Guest ShaunaMichelle]

I have wondered the same. I have read in several places that you can expect slightly smaller than your closest female relatives. But i don't know how to calculate. My moms are small - A+ cup, my oldest sister's are very small - A- cup, but my youngest sister (a few years older than me) has big boobs - C or C+ cup. So how do I know where I will land? If I land in the middle, I will be quite happy! Mine are already about the same size as my oldest sister's lol.

I think the amount of growth my also be affected by the age at which you start HRT, but I may be wrong about that.

Grow baby grow!

Oh god!!! One cup smaller than my mom would give me D's if I ever started Hrt...

Guess I would never hit my nose if I ever run into a door lol

Well before I was pregnant, I was in a barely C. When pregnant I was full overflowing C. Then after 3 girls in 4 years I am barely B now. With the super wonder bras I can pull off a C. LOL

I know of no real basis for the general rule. It has been around a long time and I know no scientific analysis on such. Basically I think the point of the rule is to say genetics has an effect but don't expect to get as much as others in your family.

Not many MTF will get up to D cup without surgical assistance.

One problem with cup size on MTF is that MTF torso tend to be much larger which pushes up the band size. Even if development has enough volume for a D cup on a smaller frame, on the larger chest it will come out a B. Sizing a bra can be tricky for MTF as larger band sizes tend to come with larger cup sizes. It is easy enough to find a 38B or 38C, but try finding a 40B and pickings get much slimmer. Get to a 42B or 44B and it is even more difficult.

[Guest Elizabeth K]

I think that is just a myth - mainly to say that your family genetics plays a part. It does I think. Because of the larger frame we tend to have - like Drea said, you will need a bigger breast size to obtain the cup sizes as listed in the standards. In other words, a 34 band with a D cup might be just a B cup if the band size is 42.

And I am already much larger than my mother...But my grandmothers were both buxom.

Also, it takes about two years to get results, at least 3 or 4 to get the filling in all around, and a minimum of six years to reach full potential. Your breasts also tend to reflect significant weight gain or loss. Think of it this way - how do a young girl's breasts develop?

Ok guess I will add my two cents to this as well. I was told at my age (38 when started hrt) not to expect much at all. Had also herd of the one size smaller then female relitivesbut also herd it was mainly for younger trans woman( late teens-early twentys). Well I guess was geneticaly gifted cause as am now larger then my sisters they are both B's. But smaller then my mom( mom is endowed 38 DD ). Depending on band size and maker I range froma 38 D to a 42 C cup. Most 42 bands just do not feel right on me at all. My best fitting bra is a 38 D it fits well is filled completely out and I barely ever notice it is on. Before hrt i was flat as a board in the chest department. Every time I think they are done growing they deside to grow some more. Have been on hrt for over 3 1/2 years now and still getting results. As is so well said here your milage may vary.

[Guest ShaunaMichelle]

Megan - I am totally jealous (although I have only been on HRT for 2 months). If I become as blessed as you I would have the biggest boobs in the family (mom and 2 sisters). Both of my sisters said they will be peed if I end up with bigger boobs than them lol. I guess I should be happy that after only two months I can fill a 36 A. Perhaps it is a sign of good things to come. And it means that mine are already the same size as my oldest sister's ;-) but she doesn't get to be mad when I "out grow" her, she's getting hers "upgraded" in the fall. So if I pass her before then, I won't be bigger than her for long.

Happy growing ladies! lol

Well - I wear a 40 bandwidth C cup. I use an extender and I use an add on horizontal strap that keeps it on my shoulders. 40 C did not fit when I first bought it but it does now. My band size actually 'measures' 41" - but there is no such thing.

Not all bras fit the same. When you find one - make sure to get at least three or four, in the event they get discontinued! It's not a real problem - two whites, a black and a beige, for example are needed (I am full time).

I also complicate it as I hate underwire and I dislike those over-padded ones.

But - I LOVE being female at last! grin - so it's just part of what we have to do!
