Post breastfeeding momma here!!
I bought the All Day Push Up as well as the Active Crossback. Long post, so I will sum up: both are very comfy, flattering, and they both give great coverage (even when you bend completely over). I wear a 32D (between a D and DD).
To everyone: First things first. I absolutely agree with "our girls recommend sizing up." I wear XS shirts and S in just about everything else, I'm a 32D (almost DD), and I definitely feel like if I was ANY bigger, the S would be too small. I contemplated returning my S for an M (they DID say to size up if you're between, and I should have listened!), but after several days of wearing it, it seemed to stretch enough to be comfortable. And let me tell you: it is actually very very comfortable. I bought this one for the sole purpose of being able to do laundry at my house without the girls falling out while staying comfortable, and it has definitely lived up to that. I was a little concerned that the racerback and the smallness of it was going to hurt my neck, but it shockingly hasn't. I've actually worn it to just lounge around the house. I wouldn't say that this is the most flattering bra I've ever worn, but it certainly doesn't make them look bad. I don't think this bra is MEANT to be sexy or super shapely but to be comfortable instead. Definitely recommend if you want something that you can do "active" work in but aren't necessarily trying to really impress someone with your shape.
To other mommas, specifically, who are looking to a new bra: Both the All Day and the Active have been wonderful with covering my lifeless girls. For other women who have been through breastfeeding, both are a winner in my opinion. Great for us girls who basically have deflated balloons on our chests. :D
