I have several of these bras. It's comfortable, fits well, the butterscotch color is a good neutral, and it works with all my clothing necklines. The ones I bought in a store were wrinkle-free, but those I ordered online required vigorous steaming to remove creases in the foam as they are packaged folded in a tiny sealed bag.

it helps a little. There are more powerful devices you can get for the same money - Lazerfish comes to mind.
