Breast Forms & Padding

Why add shape?

Some women like a fuller silhouette in certain outfits; some are early in breast development; some find it eases dysphoria; some just enjoy playing with their shape - the same way a push-up bra exists for everyone. Adding shape is optional and adjustable: you can go bigger for a night out and wear nothing extra at the gym.

The options, from simplest to fanciest

Option	What it is	Approx. cost	Good to know
Padded or push-up bra	Built-in foam	$10–50 / £8–40	Easiest start. No extra bits.
Bra inserts (“cookies”)	Thin foam or gel pads slipped into a bra	$5–25 / £4–20	Cheap, light, cool in summer. Readily available in lingerie sections, department stores and online.
Foam or fibre-fill forms	Lightweight full forms	$20–60	Light and breathable, but don’t move or feel like tissue.
Silicone forms	Weighted, soft, realistic forms	$50–300+	Most natural movement and drape. Heavier and warmer.
Adhesive silicone forms	Silicone with a sticky back	$100–400+	Can be worn with some low-backed or strapless outfits. Needs care and skin prep.

Choosing a size that looks natural

• Start with your band. Measure your underbust as usual and get the right band size first.
• Go modest. One to two cup sizes in proportion to your frame looks most natural and is lighter to carry. For many people that’s roughly a B or C cup in their band size.
• Form sizes aren’t cup letters. Silicone forms are often sized by number or weight. Each brand has a chart matching form size to bra size - use it.
• Shape matters. Teardrop and asymmetric forms sit naturally in most bras; triangle forms suit plunge bras; round forms suit balconettes.

Wearing them

• Pocketed bras have an inner pocket that holds forms or inserts securely. Mastectomy bras, many sports bras and some regular bras have them. No pockets? A snug, full-coverage bra still works, or a sewist can add pockets.
• Position: forms sit slightly to the sides, not dead centre. Nipple points face slightly outward.
• Necklines: high and medium necklines are easiest. Deep plunges and low armholes can reveal edges - a little practice in the mirror tells you what works.
• Heat: silicone gets warm. In an Aussie summer, foam inserts or a padded bralette may be more comfortable.

Caring for your forms

• Wash silicone forms with mild soap and lukewarm water, pat dry and store them in their original shell or a shaped box.
• Keep them away from pins, brooches, sharp nails and pets - silicone can puncture.
• A soft fabric cover can make them more comfortable against skin.
• Well looked-after silicone forms can last for years.

The bigger picture

Breast forms are a tool, not a requirement. Some people wear them every day for years; some for a while; some never. However you approach it, the most important fit is the one that feels like you.
