What does a 30F bra size look like?

I've realized that there is some confusion as to what this really looks like, so I decided to post my first picture!  Below, I am wearing a size S shirt, so it's not too tight.  I think this is a good shot for demonstrating that a 30F bra size is NOT GINORMOUS!  At this weight, I believe I used to wear a 34B-C before, but the band was riding up, I was getting quadraboob at the top of the cups, the wire was not enclosing enough of my breast tissue on the sides, I was adjusting all the time, etc. 

This bra lets me forget that I'm wearing one.  I never adjust anything, everything stays put (it's a Panache Cleo Eleanor size 30F).

Here are two links to GOOD bra size calculators -- notice they don't ask you to add inches. 

This one you can adjust the band/cup sizes, so you can see what the "sister" sizes are

This one doesn't show sister sizes, but it's also a good one

Sophisticated Pair also has a good explanation of measuring and sizing and some good before/after photos

So, an A cup would be a 1-inch difference between the actual underbust and the bust measurement.  If you have any kind of cleavage you are not an A!  My younger DD has in the past worn a 34A, but today she is wearing a 30D, and she could probably wear a 28DD/E, but she doesn't need the extra support, so she can get away with it.  She is 5'3.5", and very petite!

Please visit the above links, and reply with what you are wearing right now, and what the calculators say you should be wearing.  Have fun and don't freak out!  Ebay has lots of options for $20 for bras that usually go for $50-$100.

For those of you in Australia/New Zealand, I've heard on a Ravelry (knitting) forum that bras there are terribly expensive.  Most of your compatriots try on stuff at a store so they can get the size right, then order from the UK, it's actually cheaper.
