I'm the one that asked the I'm so confused question...I ended up ordering one that said US10/4xl in the pink & green (the colors are more vibrant than the picture) the fit is great & it's super comfy & I'm going to order another. However, in order to layer in the winter turtlenecks underneath I'm also going to order a couple one size up. Just to get that Xtra needed in those cold months. BTW, I'm a 38d, 5"1" & fluctuate between size 6 - 12 depending on the manufacturer.
