They are so super soft, true to size and have a nice form fitting shape. I am 5'10' 188lbs, a bit on the busty side (D cup) and the X fits beautifully. I have very long arms and I love that these top do too! The arm length comes all the way down to the base of my palm, which is so great as it is hard to find long sleeve shirts that are actually long enough for my arms.
