Actually, it's even more complicated than that. A US DDD (which is my size now) is a UK E. I don't understand why US sizes like to tack on extra D's instead of just going to the next letter in the alphabet. I also don't understand why they just skip over the letter "I" entirely.
My new Chantelle bra is a 32DDD US, 32F France, and 32E UK.
Sometimes when I go to order, DDD, F, and E are all available and I have no idea which to choose. Will I get the same size no matter which I choose? I always assume they are going by American measurements, but on the Fig Leaves website, they are going by UK measurements. If I got a 32F, it would have actually been a 32G US.
Then to complicate matters EVEN MORE, not all bras fit true to size, so you have to account for bras that might fit more generously in the cup like the Fantasie ones supposedly do.
After all is said and done, I am still not sure that either of the sizes I ordered from Fig Leaves is correct.
Writing about that just gave me a headache. Ugh.
