I think the description sums this one up perfectly. I have a curvy figure, wear an XL, and find that the fit is great for me with the slight fabric gather in front to add a little room in the hips and add a nice touch of style. The fabric is also light and comfy just as the description claims, but not too clingy, which is awesome. And when I say the fabric is comfy, it is definitely one of the most comfortable I've found lately (especially for summer)! Looks like this one is selling out quick and for good reason!
I don't know how it does it, but every Arc'teryx item I have fits me just right. This tank is no exception -- looks great on, and is incredibly comfortable, too. I'm going to just have to get all my clothes from Arc'teryx from now on, I guess.
