I initially ordered the black in Medium, which is my usual size in tops and also what the size chart recommended for my 34C/36" bust. It fits well enough that I love it, but is still slightly loose, so I ordered the olive color in a Small. It just arrived, and it fits PERFECTLY. These tops have a really cute, fitted style without being completely skin-tight, the fabric is a soft, breathable ribbed modal (a natural fiber made from wood pulp) with 9% spandex for plenty of stretch, and the contrast seams on most colors give it a sort of rugged, sporty look. (I wish the latte color had the stitching in brown so it also had the contrast!) The length is great, too - I'm 5'5" and a bit high-waisted, and the bottom of the hem falls right at my natural waist, about 3" below my bra. And it's on sale, 50% off! I'm so happy, and have already ordered all three of the other colors in Small as well. I really hope it'll be made in more colors! Dark olive/army green, burgundy, dark gray, and dark teal would be fantastic.
