The tank comes in white, light pewter, light turquoise, and navy. I ended up getting the navy for opacity. The light turquoise was so so so pretty, but much more sheer. This is such a breezy lightweight top, and I didn't want to have to wear something underneath. And you can see the model's bra in the close up pic that shows the detail. And I love the pleated detail - very pretty - it's a woven fabric inset in the knit.
Fit-wise, I went with a Medium. I tried the Small, but it (actually, I swear, because this is very rare) pulled at the bust a bit. I can see this looking a little maternity-ish if you are busty, but since that didn't even happen to me when I had each of my two darling children, I didn't have to worry so much about that.
The top is definitely swingy, but still fit fairly close to my sides and then skimmed over my hips. Pardon the IRL pics, and I took it while trying on the new purchases yesterday. Dark jeans really don't do the tank any justice, but I was hurrying. I really see this with white jeans, khakis, cute shorts. Just nothing too full on the bottom. And the detail doesn't really show up in the pic (thus the catalog pics above). For $22, I will really enjoy it this summer.
