How to Choose Silicone Breast Forms: The Complete Buying Guide
How to Choose Silicone Breast Forms: The Complete Buying Guide
Whether you're exploring feminization for the first time or looking to upgrade to a more realistic option, choosing the right silicone breast forms can feel overwhelming. Size, shape, weight, skin tone, material quality — there's a lot to consider. This guide walks you through everything you need to know to find the perfect fit for your body, your lifestyle, and your identity.
Note: Silicone breast forms are external wearable prosthetics. They are not surgical implants or medical devices. No procedures, no recovery — just wear them when you want, remove them when you don't.
What Are Silicone Breast Forms?
Silicone breast forms — also called wearable breast prosthetics or fake boobs — are external, non-surgical prosthetics designed to simulate the look, feel, and weight of natural breasts. They are worn against the skin or inside a bra, and can be removed at any time.
Unlike breast implants, which require surgery, silicone breast forms are completely non-invasive. They're a safe, reversible, and increasingly realistic option for anyone who wants a feminine silhouette — on their own terms.
At Femmevee, all breast forms are crafted from premium platinum-cured silicone — the same material standard used in high-end medical and cosmetic applications — for a feel that's genuinely skin-like: soft, smooth, non-sticky, and non-greasy.
Who Are Silicone Breast Forms For?
Silicone breast forms are for anyone who wants to feel more at home in their body. Common wearers include:
- Trans women and MTF individuals — for gender affirmation and everyday confidence
- Femboys — to complete a feminine look and feel
- Crossdressers — for a realistic feminine silhouette during dressing
- Non-binary and gender-fluid individuals — exploring expression on their own terms
- Drag performers and cosplayers — for dramatic, stage-ready looks
- Post-mastectomy individuals — seeking a non-surgical breast prosthesis option
There is no single "right" reason to wear breast forms. Your identity, your comfort, your choice.
Why Material Matters: Platinum Silicone vs. Other Types
Not all breast forms are created equal. The material determines how realistic they feel, how safe they are for your skin, and how long they last.
| Material | Skin Feel | Body Safety | Durability | Recommended? |
|---|---|---|---|---|
| Platinum Silicone | Ultra-realistic, skin-soft | Hypoallergenic, non-toxic | Excellent | ✅ Yes — best choice |
| Standard Silicone | Realistic but may feel stiffer | Generally safe | Good | ⚠️ Acceptable |
| Foam / Fiberfill | Soft but not realistic | Safe | Moderate | ❌ Not for realism |
| Gel / Water-based | Jiggly, but can leak | Risk of leakage | Poor | ❌ Not recommended |
Femmevee uses exclusively platinum-grade silicone across all products. This means zero sticky residue, zero oily surface, and a texture that genuinely mimics human skin — even under touch. It's also fully hypoallergenic, making it safe for sensitive skin and extended daily wear.
Choosing the Right Shape
Breast form shape affects how natural they look under clothing and how they sit on your chest. The most common shapes are:
| Shape | Best For | Look Under Clothes |
|---|---|---|
| Teardrop / Asymmetric | Most natural everyday look | Mimics natural breast drape; ideal for fitted tops |
| Round / Symmetrical | Fuller, rounder appearance | Great for low-cut tops and bras with padding |
| Triangle | Subtle, lightweight wear | Discreet under casual clothing |
Tip: If you're new to breast forms, a teardrop shape is the most universally flattering — it follows the natural slope of the chest and looks convincing under almost any outfit.

Breast form sizing is typically based on cup size (A through G+) and chest width. Here's how to find yours:
- Measure your chest circumference — wrap a tape measure around your ribcage, just below where your breasts would sit.
- Decide on your desired cup size — think about the look you want and what feels proportionate to your frame.
- Check the brand's size chart — sizing varies between manufacturers. Always refer to the specific product's size guide.
| Cup Size | Approximate Weight (per form) | Best For |
|---|---|---|
| A – B | 150–300g | Subtle, natural look; lighter frames |
| C – D | 300–500g | Most popular; balanced and realistic |
| DD – E | 500–700g | Fuller figure; dramatic silhouette |
| F – G+ | 700g+ | Maximum volume; cosplay or stage use |
First-time buyer tip: Start with a C or D cup. It's the most versatile size — realistic enough to be convincing, light enough for all-day comfort.
Understanding Weight
Weight is one of the most overlooked factors — and one of the most important for comfort and realism.
- Heavier forms move more naturally and feel more realistic, but may cause fatigue during extended wear.
- Lighter forms are more comfortable for all-day use but may feel less convincing under touch.
- Platinum silicone has a natural density that closely matches real breast tissue — so Femmevee forms feel weighted and realistic without being unnecessarily heavy.
If you plan to wear breast forms daily, prioritize comfort. If you're wearing them for specific occasions or photography, you can go larger and heavier for maximum visual impact.
Skin Tone Matching
For the most realistic look, choose a breast form shade that closely matches your natural skin tone. Most brands offer options ranging from fair to deep. When in doubt, go one shade lighter — silicone can appear slightly darker against your chest due to shadow and lighting.
Femmevee breast forms are available in multiple skin tones, each carefully formulated to match the warm, natural undertones of real skin.
How to Wear Silicone Breast Forms
There are three main ways to wear breast forms:
- Inside a bra pocket — the most common method. Many mastectomy bras and femme bras have built-in pockets designed to hold breast forms securely.
- With medical-grade adhesive — for a seamless, bra-free look. Use only skin-safe adhesive designed for silicone prosthetics.
- Inside a compression garment or camisole — a comfortable, low-profile option for everyday wear.
Care tip: After each wear, gently wash your breast forms with mild soap and lukewarm water. Pat dry with a soft cloth. Store flat or in their original case — never fold or compress. Properly cared for, platinum silicone breast forms can last for years.
Frequently Asked Questions
Are silicone breast forms the same as breast implants?
No. Breast implants are surgical devices inserted under the skin by a surgeon. Silicone breast forms are external wearable prosthetics — no surgery, no recovery, no permanence. You simply wear them and remove them as you choose.
Are silicone breast forms safe for daily wear?
Yes — when made from platinum-grade silicone, breast forms are hypoallergenic, non-toxic, and safe for extended skin contact. Femmevee uses only platinum-cured silicone, which is free from harmful plasticizers and won't degrade against your skin.
Can I wear breast forms in water?
Silicone breast forms are generally water-resistant, but prolonged submersion (swimming, bathing) is not recommended as it may affect adhesive bonds and long-term material integrity. Check your specific product's care instructions.
How long do silicone breast forms last?
With proper care, high-quality platinum silicone breast forms can last 2–5 years or longer. Avoid sharp objects, extreme heat, and harsh chemicals.
What size breast form should I start with?
For first-time wearers, a C or D cup teardrop shape is the most recommended starting point — realistic, comfortable, and versatile across most outfits and body types.
Do breast forms look real under clothes?
Yes — especially platinum silicone forms, which move and drape naturally. Under fitted tops, dresses, or swimwear, a well-fitted breast form is virtually indistinguishable from natural breasts.
