The material is too thin an clingy- shows bra lines and too many imperfections

so I would suggest a dark bra or something underneath

It's a little see-through in the chest where it's a bit taut, but I just wear a dark colored bra and you can't tell

It got a bit sheet across the bustSo I will need to wear a darker bra

I did buy one size larger that recommended as I am aware most of their clothing runs small
