I have two of these wraps,I'm 5'9 and 133 pounds and I got a small, and it fits fine.
I have one in black, one in white.
The black one has held up remarkably well, minimal color fading and almost no pilling. A perfect, zero maintenance garment that can be worn all year long. I use benzoyl peroxide on my back in the summertime, and there was almost zero bleaching effect from the wrap touching my bare, sweating skin...you can barely tell any bleaching from the wrong side of the garment and not at all from the right side. That is a miracle, you have no idea how many good shirts I go through in the Texas summers due to that bleaching effect. I try to hand wash it, but otherwise I toss it in with my darks in a lingere bag. I lay it out to dry it unless I'm in a hurry.
All in all, this wrap IN BLACK is one of the most versatile, highest quality, perfect items I have ever adorned my body with. I recommend it highly.
My wrap IN WHITE however, not so much. After the first wear, it was showing tiny little holes, in random places. I stitched them up, which worked, but what a pain! The seams on the shoulder are loose and look like they may fall apart. There is a big gap now between the sleeve and the shoulder, attached only by loosely woven threads. And of course its white, so there are now stains under the arms from sweating. The fabric is more delicate and started to pill and show wear within a few wearings. Its still wearable, but if I had purchased this one first I would not of bought another.
I am so impressed with the quality of my initial purchase...the black wrap...that I have to give this 4 stars. But I take one off of 5 for the white one being so disappointing.
