Cleavage enhancement may also include the use of makeup to deepen the appearance of the cleavage and make the breasts either side of the cleavage appear more prominent.
In movies and theatre, an actress who has smaller breasts than the character that they are playing may need to use cleavage enhancement techniques to present the image required by the role. For example, Julia Roberts was required to wear a water-padded bra for the movie Erin Brockovich in order to increase her apparent breast size and enhance her cleavage.
Male cross-dressers often want to create the illusion of female cleavage as part of making their body appear feminine. Many crossdressers believe that displaying a convincing cleavage will distract attention from flaws in their appearance and will improve their ability to pass. Because most such males have little or no breast tissue, some form of skin pulling technique is used, often in conjunction with the use of makeup to increase the illusion.
Cleavage enhancing bras are most commonly referred to as push-up bras. They vary in design from unpadded designs which simply push the breasts towards each other through to moulded cup designs with large moulded pads in the bottom and outside of the cups to force the breasts upwards and inwards.
Some cleavage enhancing bra designs incorporate removable pads to allow the extent of the push-up effect to be altered by the insertion or removal of pads.
Padding used in bras has been manufactured in a variety of styles, including sealed bags containing air, water or some form of liquid or gel, and from semi-rigid materials such as moulded polyurethane foam rubber.chicken fillets.
Use of the wrong techniques or tape with too strong an adhesive can cause injuries such as rashes, blisters, and skin being torn off.
Adhesive gel bras consist of two shaped silicon gel filled bra cups that stick to the skin of the breast using built-in re-usable adhesive, then clip together to pull the breasts together.
These can be used as falsies that won't slide around in a bra, and can be used to enhance cleavage on a woman by using them in their originally designed manner.
For cleavage enhancement purposes, these gel cups can be applied towards the bottom and outside of the breasts and then the clip done up to pull the skin together. They have advantages over techniques of pulling the skin forward, as there are no straps and they are widely and cheaply available. Some users deliberately wear the cups upside down by swapping the cups left-to-right.
At least one website markets the same gel bras as sold for women as being a special product for crossdressers.
Using a skin pulling technique and pulling the skin too tightly or wearing a bra that is too small in the cup size will create excessive bulges either side of the cleavage, which will look obviously pushed out of shape.
Either pulling the skin too little or showing too much of the peaks of the bulges created by a skin pulling technique may cause the curvature of the cleavage to be visibly different from the curve that would exist for real breasts of the same size. The parts of the breasts visible in the cleavage will appear to curve away in a manner that does not line up with the rest of the breasts.
Excessive or poorly applied makeup may look obviously false and may detract from an otherwise effective cleavage illusion.
