I believe there are a few things to confirm if you're wearing "the right" size. Given the variability, no guarantees. ;-)
- Qudarboob: When the cups cause a depression on your upper breast tissue.
- Red marks from the bra on your body (Notice underwires and bands the most. I think it's sad to see the flesh constricted, it's bad for lymph, and circulation. Also looks horrible, but I can't comment on the need to lose weight, I'm an offender. )
- Band rides up or drops low in the back
- Cups tilt
- Cups bubble out

In addition, there's the precise fit: Are you full on top, or full on bottom?

Look for blogs "The Full Figured Chest," "Sophisticated Pair" and Hourglassy.com. They might be more helpful, as they get into more details. I can tell you a little, but the two blogs do reviews, so there's more information there. :-)

Good luck!

I find my breasts are fuller on the bottom than the top.
When you say the cups tilt, what do you mean? I find the underwire towards the middle kind of tilts away from my ribs.

I find that if I wear my bra for a very long time there are slight marks from the band however wearing a 40 band size does not give me the support I feel I need and slides around a lot.
