Natural Triangle Breast Form: by Transform

Natural Triangle Breast Form: by Transform - Main image
$120.6 $180 In stock

The Natural line of Breast Forms were crafted to be the most authentic looking breast form available. The Transform Natural Triangle Breast Form is more elongated with a higher wing than the full triangle styles; the tapered wings become gradually thinner to blend smoothly into the chest. The wider shape provides more fullness on the sides. The apex and the nipple are lower, and the belly of the form is wider for more fullness at the bottom of the cup.

Complete your look with Breast Forms by Transform.

These breast forms are designed to be worn with the Transform Pocket Bra. Also available is the Oval Breast Forms.

This shape and style is available in two tones, and in sizes 4, 6, 8, and 10.

Everyone wants to look great in their clothes, and wearing the right undergarments can make all the difference in how an outer garment looks and fits. Different prosthesis styles will fit differently in different style bras. Therefore, the most important things before choosing a breast prosthesis are to fit the right bra size and choose the right bra style. 

How to Fit Breast Forms:

  • Using a tape measure, measure around the rib cage under the pectoral muscles where the natural breast tissue joins the body. Take a snug measurement. (This would be where the band of the bra fits around the chest.)
  • Add 5 inches to this measurement.
  • Example: Chest Measurement = 36″ Add 5″ Estimated band size = 41″.
  • Bra bands come only in even numbers, so this person would try on a 40 or 42 to see which works best. All bras stretch differently.
  • The Band Size stays the same, no matter how large or small you want your breasts to be. For the size of the breasts, choose a cup size letter.
  • Consider height, weight, and figure style. If you are 5’10” tall and a 42-46 bra size, generally choose a C, D, or DD cup bra. If a size 34, 36 or 38 bra, choose a cup that balances the figure like a B or C cup. If you choose a cup size that is too large for a small frame, it may be harder to buy clothes. If you choose a cup size that is too small, and you have wide shoulders, or a big waist, your forms will not fill out your clothes.

After you choose your cup size, use the chart below to find the corresponding breast form size. Breast form sizes vary by style with some up to size 14. See individual product descriptions. If two sizes are suggested (ie. 2/3) try both to see which fits best for you.

  • Lengthen the bra strap on one side.
  • Pull the cup away from the chest wall.
  • Insert the form from the inside top of the cup. Turn the form in the direction that best fills the bra cup and looks the most natural. Repeat on the other side.
  • After forms are in place, adjust the straps on each side.
  • Look at the fit. Both sides should match and the bra cups should cover the prosthesis completely. The prosthesis top tapers should prevent clothing from sinking in. Each form should fill and not bulge at the top of the cup; plus, the forms should settle into the bottom of each cup. The straps should not cut into the shoulders.
  • If the forms are too big, too small, or do not fill where they need to fill, try another style or size of form.
  • Spread the bra out on a flat surface with the inside of the bra facing you.
  • Hold the form by the edges with a flat hand so that the nipple is facing down.
  • Spread the elastic on the cup and slide the form in so that the nipple faces outward.
  • Adjust the form so it settles into the bottom of the cup.
  • Hold the bra up with the form inside the pocket to make sure it looks correct.
  • Be careful not to puncture the form or fold it. TRANSFORM® silicone forms are very durable, but the polyurethane skin can be punctured.

Measure to Determine your Bra Band Size

Choose a Cup Size

  • The Band Size stays the same, no matter how large or small you want your breasts to be. For the size of the breasts, choose a cup size letter.
  • Consider height, weight, and figure style. If you are 5'10" tall and a 42-46 bra size, generally choose a C, D, or DD cup bra.

Putting Forms Into a Regular Bra

  • Lengthen the bra strap on one side.
  • Pull the cup away from the chest wall.

Putting Forms into a Pocket Bra

  • Spread the bra out on a flat surface with the inside of the bra facing you.
  • Hold the form by the edges with a flat hand so that the nipple is facing down.
  • Spread the elastic on the cup and slide the form in so that the nipple faces outward.

Customer Reviews (4.8 / 5 · 5 reviews)

Hazel ★★★★★

The higher wing on this triangle shape actually sits flat against my chest instead of rolling up like my old pair did. Wore it under a fitted dress for a wedding and never once had to adjust.

Henry V. ★★★★★

I was worried it'd look obvious under a fitted top, but the higher wing blends right into my chest without any harsh edge. The triangle shape gives a really natural slope too, way better than the round pair I had before.

Owen ★★★★★

The elongated shape and higher wing sit so naturally under my clothes that I forget I'm wearing them. The texture feels remarkably close to real skin, which was my biggest concern before buying.
