What do you think how long should I take wonderup to see the results. And I have question what is the difference between two cups for example a and b cup? One inch?
Thanks

Whatever you try you should be prepared to continue with it for 3 months at the very least. Some people here would say longer than that, as I can remember 6 months being recommended more than once.

I think that is how bra sizes basically work yes. Don't forget there is a page on this site for bra measuring (to go main menu, then choose the 8th option on the right hand side - bras and breast measuring).
