difficult to choose a size

I usually make the 42 but I have a strong chest. After 2 successive deliveries, I still belly but as I lose weight regularly, not easy to choose a size since not really want to buy a jersey and have to buy another one in a few months.

After reading various reviews and my own experience, here are my conclusion:
1) for larger people but have a chest "normal" (up to 95 c or d) or small. Feel free to take your size and not larger because the jersey is elastic, and fasteners are set around the neck and back by making knots.
2) for small individuals and small chest, would it be better to take a size less.
3) for those with large breasts (and do not intend to lose several kilos) take one size bigger.
I opted for the 40/42 (after hesitation with 42/44) but the chest is all right.

The jersey is very nice, well-cut and flattens a little stomach for a small flat stomach after effect ... there is no miracle either; o)
