I first saw this online and was worried the design might look awkward in real life...not on a model, but tired it on in store and it looks great!  it has a tighter fit and seems to flair out in just the right place.  just the right thickness, not too thin or thick.  i am 5'6", 124lb, 34b and got the xs.  i did not try on the s for comparison as i thought the xs fit great.  i'm always either an xs or s with retailer tops. blue is definitely more steel. interesting piece! will not disappointed!
