@Bonkers1 - I'm a huge fan, but I wasn't at first. When I first tried it I said "no way." But then I saw a video with the vendor, in which she was allowed to explain things, and she said "too tight, just right." I gave it the three days she recommended, and now I don't want anything else!
I don't consider myself well endowed, but I am full figured, which a bra fitter once told me meant my breasts are spaced apart.
In any bra I always kind of lean forward a little and put them in (the fitter taught me that too - I never did it.). I think that might be what the vendor meant.
BTW I don't "step in," I pull it over my head, then adjust it.
I wore nothing but contoured underwires for as long as I can remember. I didn't dare wear anything that wasn't an underwire. These have made such a difference!
It's too bad some hosts don't let vendors talk more about what they're selling. They know their products best. Let them talk about it, especially during the midnight introduction!
