Soft curves, smooth lines, and a shape that wraps you inward — InverSoft is designed for those who love surrender with a feminine twist.

Its inverted, petal-like structure guides everything gently inside the shell, creating a tucked, delicate silhouette that feels both playful and transformative.

The design encourages a softer posture and a more submissive aesthetic, making it perfect for sissy roleplay, gentle domination settings, and fantasy-driven transformation play.

Lightweight, comfortable, and naturally restrictive, InverSoft turns control into something elegant, sweet, and beautifully unavoidable.

You slip it on and feel everything drawn inward — quiet, gentle, contained.

It’s subtle at first… then unmistakable.

A little tighter. A little softer. A little more you.

InverSoft doesn’t lock you away — it invites you deeper into the role you’ve imagined.

SIZE CALCULATOR

Measure manually for the base ring

Measure the circumference around your cock from behind the balls. You can use a fabric tape measure (the kind dressmakers use) to get the measurement, or, if you don’t have one, you can use a piece of string and a ruler. Wrap the tape measure or string around your cock, going behind the balls. The tape should be snug but not tight.

Now you have your circumference you need to divide it by 3.14 to get the diameter. We’ve done some sample calculations below to show you how it works:

In imperial:7 inches ÷ 3.14 = 2.25 inches diameter
6.25 inches ÷ 3.14 = 2 inches diameter
5.5 inches ÷ 3.14 = 1.75 inches diameter
4.7 inches ÷ 3.14 = 1.5 inches diameter
