I didn't like the stretchy, no fastener bra made by Spanx so the Ahh bra was never on my radar.
I used to be an H cup. Real size not the size we often think we are. Now, I wear either a D or C depending on the brand. I still can't find anything that's comfortable. Sometimes I just wear sports bras. That's as close to comfort as it gets. Wide shoulder straps are a necessity. Smooshing them down is a little bit of heaven. lol
