Bra Inserts, Push-Up Pads, and Breast Forms: What's the Difference?

You may have seen the terms "bra inserts" and "push-up pads" used interchangeably. They can mean the same thing, but not always.

An insert is just anything you put inside a bra, and does not always add size or lift, while push-up pads always do this. The amount of increased size and lift that a push-up insert provides depends on its diameter, thickness, and placement inside the bra.

Push-up pad bra inserts are often thicker at the bottom, gradually thinning out at the top. Above left is an example of this type of insert, sized to fit inside A and B cup bras. These can be used for one breast only to even out asymmetry, or as a pair to provide enhancement for both.

When shopping for push-up pads, look to see if they are sewn around the edges rather than free-cut foam. They can do what you want either way, but reinforced sewn edges will help them keep their shape longer during washing and wearing.

For the most lift, place push-up bra inserts at the bottom of your bra and settle each breast into the cups above them. To bring your breasts closer together for enhanced cleavage, put the inserts at the outsides of the bra with the thinner halves facing inwards, and scoop each breast in towards the center.

What about breast forms? A breast form (shown at right) is a full artificial breast prosthesis made out of silicone gel, foam, fiberfill, and/or polyurethane.

This will usually have a flat back, and is meant to be worn inside a mastectomy bra with a pocket to accommodate it. A breast form can also be worn inside a regular underwire bra for those who can tolerate underwires, as long as the form is the right size.

Breast forms come in sizes like bras do. It's best to look up the size chart that is specific to the brand of your breast form to get the most accurate information about its sizing, but Google has a general guide.
