It’s a bandeau bra. Bandeau bras give you a natural shape and minimal support. They're also known as tube bras. These bras are useful in a strapless or halter neck dresses. If you want lift your breast then push up bra might be a perfect option for you. Push bra are designed to provide illusion of bigger bust, while offer comfort, support and little extra cleavage.

I highly doubt it. Most bandeaus are made of stretchy material and are designed to look pretty, rather than support. There are plenty of no padding bras made of non stretchy material, like these http://www.herroom.com/search2.aspx?terms=unlined+...

In general, if you're looking for support, stay away from camis, and make sure your band is tight enough that you can only get two fingers under it.

depends on your size...

They are not designed to lift, just cover
