This has been a major staple in my wardrobe. I love how the tank top is so long and never rides up. It's smooth and isn't bulky when I layer clothes over it. I have one in black and one in white and I wear them constantly. I could see myself wearing these post-baby too. I am a size 12 pre pregnancy with a large bust so I got a L/XL. I could've maybe gotten away with a smaller size, but they're so stretchy it doesn't matter....haven't hit the third trimester yet either so it may be perfect!
I love these tanks. I wore one almost every single day with all three of my pregnancies. At 5'11", I loved the fact that it was very long and I never had to worry about the bottom of my belly hanging out. And it seemed to help keep my pants up the way a band does. It is more of an undershirt then a regular tank top because of the sheer material.
