Ookay, let's try to not get mixed between US, French and European sizes...
In French size, I am currently depending on the clothes, a 38, 40 or 42. Which would be... 36, 38 or 40 in Euro sizes... so if my conversion is right, that would amount to a 6, 8 or 10. But it really depends. On average, I must be a 6-8, and more a 8-10 on the hips. (It'd help if clothes manufacturers used the same measures, though. This is so confusing.)
I may still lose one more size, but I'm not sure I'll go lower than that. I don't even know what size I'm supposed to be. The last time I was at my current weight was when I was 11, so...
