inserts for cleavage

Any recommendations? I don't really want to add size, just push-up and have some cleavage in my wedding dress.

I've seen a lot of gel/silicone ones...they seem to be better than cloth because they stay put more right?

Any one try cleavage cupcakes? They seem to be good, but I want to know before I buy.

Thank you!

I didn't use these for cleavage purposes, but I did attempt to use it for a bra once.

Stay AWAY from the chicken cutlet ones that DB sells. They like, fell right off of me. It was terrible and I couldn't use them.
