My boobs are different sizes?!

Its normal. I'm about two sizes different too, and so are a few of my friends. In fact, almost every woman is a wee bit lopsided, some more than others. To imporve the way it looks, buy a bra that has removable water or gel inserts. Get one that fits your bigger breast without the insert in. Then, just wear an insert on your smaller side.

Are you still a teenager? It's fairly normal while you're growing. Maybe try and get a swimsuit that is slimming - might make it less noticeable (even though honestly, you're probably the only one that notices).

I was a teenage girl once too.

Sometimes it happens.. And it's unlucky when it does. A lot of women in that situation get an implant in the smaller breast. If you don't want to do that.. You can always get a special bra with a pad in the smaller breast.
