I bought this too for a festival and it was super cute and light weight material. I would have to agree with the other review the material is like a swimsuit but I did not mind that. Overall a very nice top and not see through either.

The fabric is giving a swim top. For girls with little bellies and some rolls, it rises as you move and sit down. It is not like cotton or any regular t-shirt material. it does hold your breasts up nice tho
