I measured the white one I have listed for you. Thought you wanted to know on it. This tangerine one is marked XL, It measures 50" across hip area, 36" across bust area, but there is elastic so it stretches. I wear a 12 and it fits fine. I would think it might even fit a 14.
I just wanted to comment that I will ship this first class with confirmation tracking and I always ship within 1-2 days after you send me your address.
