This style of corset most likely will not give you the results your looking for. It doesnt have a underwire which generally doesnt offer any lift to your clevage but more of a flattening look which is never good. Even if you used some soft gel inserts I would stear clear of this one and go for one with some support or underwire.

I've read reviews that say it pushes your boobs down and there are no cups or underwires to lift it up.

I dnt think so but there are sum that dip in clevage area and might be able to help with that.
