Did Nami undergo a breast operation by Chopper? ;-)

All joking aside!

**How could an 18 year old girl's breasts grow so large within 2 years?**
After the time skip, Luffy became 19 and Nami turned 20. I know that in the
world of One Piece, everything is possible, **but why did the producers change
her breasts?**

This cannot be a coincidence:

question
one-piece
What's up with Nami's breast size?


I doubt there is a legitimate plot based reason for this, and it's more to do
with giving more fanservice to the audience and perhaps the animators refining
the character design over time.

Oda answered this question himself in [Volume 36, chapter
342](http://onepiece.wikia.com/wiki/SBS_Volume_36#Chapter_342.2C_Page_126).
**Nami's breast grew so much, because she was still young and in her growth
phase.** Especially with the two years timeskip, they had plenty of time to
grow!

After I ended up reading more of the SBS answers, more measurements were
revealed. So as we are all curious as to the question _how much_ they have
grown, I will additionally post those in the answer, **Nami's sizes!**

In [Volume 6, chapter
49](http://onepiece.wikia.com/wiki/SBS_Volume_6#Chapter_49.2C_Page_104) Nami's
[Bust/Waist/Hip (BWH)
measurements](https://en.wikipedia.org/wiki/Bust/waist/hip_measurements) are
revealed to be **86/57/86**.

> 57! H 86!** No doubt about it!! But she's so cuuuuute. She's definitely a
> thief. But I still like her!!

Later in [Volume 37, chapter
353](http://onepiece.wikia.com/wiki/SBS_Volume_37#Chapter_353.2C_Page_146),
which was still before the timeskip, it was revealed that her bust size had
grown to 95, making her new BWH measurements **95/55/85**.

> **Reader** : Hi, Oda-sensei! In Volume 36 you were saying that Nami's

>  Nami: Height 169 B 95 W 55 H 85. Robin: Height 188 B 99 W 59 H 89

Later, in [Volume 42, chapter
406](http://onepiece.wikia.com/wiki/SBS_Volume_42#Chapter_406.2C_Page_146),
which was again before the timeskip, Oda confirmed that Nami's and Robin's
breasts were **I cups**.

> **Reader** : I am "Sogeking-ko", a proponent of all healthy young boys

> Boys... can you accept this answer??

> But you know, the boys aren't gonna read any of these complicated, difficult

> Robin are I cups. Wow.**

Finally, in [Volume 69, chapter
686](http://onepiece.wikia.com/wiki/SBS_Volume_69#Chapter_686.2C_Page_166),
after the timeskip, her new size were revealed to be **98/58/88, J cup**. It
seems like she had grown a bit more. I wonder when her growth phase will end.

> **Reader** : About the mystery of Nami-san's New World bust size from volume

> Robin- B: 100 (J Cup), W: 60, H: 90

For body size her breasts are far too large to have not been enhanced. They
get so large due to maturity, but usually only going up a cup and a half to
two cups in size, and a lot of this is also determined by body mass. With her
body size and figure she would have not naturally grown breasts that large
without outside aid.

Granted I am speaking from a real life perspective, and with a toon you can do
all sorts of illogical body proportions. I think this is mainly to attract
male readers who for the most part don't care unless it has boobs and a tight
butt. XD
