Just got this top in the mail today, and i love it. i bought the white in a small, and it fits as pictured on the model. the fabric says it's cotton, but it's a substantial fabric and feels as soft as silk. the bodice is lined, so no bra lines show through. the tiered part of the tank is not lined but is not really sheer or see-through. the arm holes are not too large, as sometimes happens on me when i wear sleeveless tops. i think i'll be wearing this one a lot this summer, and a lot of summers
