This calculator helps you determine how sheer a fabric is. You'll select the fabric type and color, and the calculator will provide a 'Sheerness Index' score. This score estimates the fabric's opacity, helping you predict whether it might become see-through under certain lighting conditions. A higher score means a more opaque fabric.

Choosing lingerie with the right level of sheerness is important for both modesty and style. A fabric that's more sheer than you expect can lead to a wardrobe malfunction, while a fabric that's too opaque might not give you the alluring look you desire. This calculator helps you make a confident choice by giving you a better understanding of a fabric's transparency.

The 'Sheerness Index' is a guide to a fabric's opacity. A very low score indicates a very sheer fabric, like fine mesh or lace. A high score indicates a completely opaque fabric, like a thick cotton. Use this index to choose the right lingerie for the occasion. For everyday wear under a t-shirt, you'll want a high score. For a special occasion, you might choose a lower score for a more daring look.

• White fabrics often become more sheer when wet.
• A fabric's sheerness can change in different lighting, like direct sunlight or camera flashes.
• Seamless, skin-toned lingerie is your best friend for wearing under light-colored or slightly sheer clothing.
• Don't be afraid to play with sheerness as a style element. A beautiful lace bra peeking out from under a sheer blouse can be a very chic look.
• When in doubt, it's often safer to choose a slightly more opaque option.
