You know, there are so many of us on the boards now it can be hard to keep up with everyone! I also have a hard time acknowledging all the posts, but I hope everyone knows we just pop in and out and check on one another. It is a nice little community.
When I looked at your photo I also thought "tiny hinny"!

There are a couple really good sites that have instructions for bra fitting, but nothing beats a good professional fitting. I find the best lingerie people at Macys or Nordstrom’s, but if you can find a good high quality lingerie shop they normally know their stuff.
For online sites try Figleaf or Wacoal-America
