This top is very comfortable. I am 20 weeks and it fits nicely, and I can tell it will grow with me. I was worried that a maternity top would have a "circus tent" effect but this is very flattering with room to grow. I ordered my pre-pregnancy size and was not disappointed. I do recommend going up one size if your breasts have grown a lot since getting pregnant, it's a bit snug in the top, but the stretchy panels help a lot with that. I weighted 150 and wore a 34B bra before pregnancy and got an extra small, which is what I wore before, and I'm happy with the fit.
