Seriously, if you have not done this recently, you are wearing the wrong size bra.
Repeat: you ARE wearing the wrong size bra.
I saw a link on Pinterest about proper bra fitting the other night. And don't be dumb, if you're all like "I went by the instructions in my VS catalog and ordered the size they said I was, and my bras fit me ok," I have some words for you: get your head on straight and go get fitted for real. I took a measuring tape and followed the instructions. I had been wearing a 38DD, which I thought fit me well. Uh uh. Turns out I'm a 36H. H!!!!!!!!
Went to Nordstrom yesterday... Nordstrom has skilled bra fitters who know what they're doing, and a huge range of sizes in store... She doublr checked my size, and when I put on that 36H, it was like the skies had opened up, I could hear angels singing, and my boobs were so happy. For the first time in I don't know how long, maybe ever, I was like, "now THIS is how a bra is supposed to fit."
I would NEVER have reached for a 36H. Ever ever ever. I mean, wtf?! Who knew they even came in H cups. But I drank the kool aid, and I'm never going back. I did a side by side wearing my old bra and new bra, and the difference is amazing. I look like I lost 5 lbs, just from wearing the correct size. Finally.
Mother's Day is coming. Make yourself go, get professionally fitted, preferably at a Nordstrom or other lingerie specialty boutique, and treat yourself to a new bra in your correct size, which I PROMISE you is nowhere near the size you're wearing now.
Here is the link to the fitting guide, sorry not clicky. There's some colorful language in there, be warned. But it's good info nonetheless.

Nordstrom.com, figleaves.com, herroom.com are all great online resources for bras in a really wide range of band and cup sizes.
End long asss rant. Whew.
July 20th, 2012: Never forget the day the fb douchebags tried so hard, but ultimately failed. Viva la October 2011! Yeah, I called you douchebags.

Re: PSA: Go get fitted for a bra. STFU and DO IT.
I live nowhere near a Nordstrom, either. VS is still an hour or so away.

I'll second the hashtag small town problems!
I don't think there's a Nordstrom's in my state, and I live at the far north of my state. I was fitted once at Lane Bryant but that was years ago. I too, am positive I'm wearing the wrong size. I don't really know where to go to get properly fitted. I will be going to Portland,ME in a couple weeks so hopefully I can find something there.
No!! 34b/36b!!
Now THIS is IMPORTANT BUSINESS!
Tsaw:
right, it's important business. Glad we're on the same page.

Also, please do not get sized at Victorias Secret. I made this mistake once and every bra I tried on did not fit. So either the girl was not sizing me properly or the bras weren't right.
Either way, there are better places.
VS will "convert" your size to something they carry in store. So like when I was a 32DD they would tell me to buy a 34D but the band was always too big even on the smallest setting and my boobs would pop out of the cups.
I COULD NOT AGREE MORE.
And yes, Nordstrom kicks *ss for bra fitting. JC Penney, Victoria's Secret and other stores do not.
If you live in a town with an Allure, they are top notch as well.
Believe me, paying $70 for a bra that fits you perfectly is well, WELL worth it. I'm happy, my boobs are happy, and you will be happy, too. I guarantee it.
