SOS! One of my boobs is bigger than the other

Oh hey there. Can you just do something real quick? Put your hands together. Are they exactly the same size? What about your feet? Your earlobes? Your nostrils?

Thought not.

Fact fans: it’s actually super rare for people to have identically symmetrical features. Instead, it’s much more likely that your DNA will have looked at its handiwork, said, “I mean, that’s probably close enough,” and gone out for lunch.

Boobs too?

Yep. In fact, it’s actually more common for women to have one boob that’s bigger than the other than to have two identical ta-tas on their chest.

During puberty, as breasts buds turn into actual breasts, it’s likely that one will come out of the starting gate first. It could be Righty-McRightson or it could be Queen Lefty VI. Either way, throughout your teenage years while your boobs are still developing, it’s likely that they’ll grow at different rates.

So this is a temporary thing?

Well, no. Even when they’re fully developed, most women’s breasts are still different sizes. Just like their feet. Or their earlobes. Or their nostrils.

TL;DR? Here's the important stuff:
  • Breathe, it’s actually super common. It's actually more common than perfectly symmetrical breasts.
  • During puberty, it’s likely that one will develop faster than the other. They’ll probably continue to grow at different speeds throughout your teenage years, and most adult women still have one that is bigger than the other.
  • This shouldn’t affect your life in any way other than making bras shopping a bit more of a puzzle. But always buy the size that fits your bigger side, as a general rule of thumb. Or boob.

What can I do about this terrible tragedy?

There are lots of things you need to think about right now. Homework. The difference between ‘effect’ and ‘affect’. Whether or not you ever want to do a bungee jump.

This is NOT one of those things. We promise. Just like the great eyebrow mantra, your boobs are sisters, not twins. Having one a little bigger is totally normal and the chances of anyone else noticing, or caring, are basically nada – so cross it off your list right now.

Seriously, cross it off.

But wait, what size bra do I buy?

Relax, no need to start sewing two bras together into a mutant franken-bra (although hey, it’s a project). The general rule is always buy a bra to fit your bigger boob. It’s sizest, we know, but it’s better to have a little extra room than a nipple that keeps escaping every five minutes.

If you find you’re still really worried about how different your breasts are, go and have a chat to your doctor. They should be able to put your mind at ease, or suggest some other options.

And remember: in real life, the only things that are properly symmetrical are the Taj Mahal, Kit Kats and Gigi Hadid’s face.
