A few things: this runs very large. i'm usually a s/m (i'm a little busty so i sometimes size up!) and i'll definitely need an xs in this, i'm swimming in the small. the blue is definitely a steel blue/grey, not really navy. the material is very thin - i thought it would be a bit more substantial. it's very lightweight. that said, it's very pretty, i love the neckline which can be worn as a cowl neck or off the shoulder, and i'll give the xs a shot instead!
