I ordered it in my regular size 4, but I've got to say, something feels off about it! It fits tighter and the armpit cut is higher than the other cool racerbacks that I have. It actually gives me some dreaded armpit fat! I can pull it down a bit more and then it kind of goes away, but.... no likie!!!
Look how it cuts into the armpit, and is somewhat sheer as you can see my mostly-black-with-some-colors sports bra under:
I'm also not crazy about the bottom hem... why can't they make it straight?? It may not be that big of a deal because I never pull my cool racerbacks all the way down. I usually just let it kind of bunch up a little at the bottom. But still!
So I laid this cool racerback on top of an old one that I have (raspberry) in the same size, and as you can see, it is cut smaller by about a quarter of an inch on each side. That translates to about an inch all the way around, and I think that's quite a big difference! You can also see that the armpits are cut higher than the old one, though not by as much as I would think judging by the way it feels when I have it on. Maybe the combination of being cut higher and tighter makes a bigger difference...
Here's a closer up of the tag... it is made mostly of poly. It is not too soft, but it is not as rough as some of the older polyester cool racerbacks had been.
So I'm kind of disappointed in this one! I love the way it looks, and the angel wing color is a beautiful cream color. But maybe I need to try a size 6 and see if it would fit better. I've never bought a cool racerback that wasn't a size 4 before! I sure hope this is not the new direction Lululemon is going with their cool racerbacks. If so, I will be hard pressed to buy another.
