No Idea.. I am a 46 DD to a 42 K depending upon the bra and it would fit me easily.. Sorry I couldn't answer that question anymore.. For a previous question, I put my hand inside and the velvet knit is a good quality so you are unable to see through it. If you are smaller in the shoulder area, it might slide off the shoulder a little. I like that kind of style though which is why I initially bought it. I hope this helps...
