This is a very nice workout top. Although it is loose, it actually drapes very well and is complimentary enough for casual wear. I have an hourglass shaped body, and the fabric curves into my waist and gently sits on top of my upper hip, so it looks like it's fitted even though it's cut straight. The sizing is exactly as listed in the chart. The nice part is that I bought this in XL (I'm usually a L) so when I lift my arms, the top doesn't bunch up around my waist. It just drapes back down my hips. No more tugging and no more sticky arm pits making my shirt cling to my skin. The air flows through fabric very nicely, and the looser fit allows air to flow into the top. I don't understand why the back is cut into a triangle design, because there's no extra ventilation. But it does give you the illusion of curving inward along the waist, which is a nice touch. The tulip hem allows for easy access, so you don't have to lift your top to get into your pockets. I'm 5'3", so the high-low hem hits just below where my thighs start, and just below my rear end, so it's great for modesty purposes. The shoulder seams hit about one-inch past my shoulders, but it doesn't look like an oversized, slouchy top. The fabric is light weight with no texture and has a distinct polyester feel. I wish it were thinner and more silky, but I don't wear this as a fashion top, I wear it to workout. I am very happy with this purchase. I bought six more for every day of the week.
