Illumination Bikini

Bikinis are low-rise and sit on the hips, with thin sides and a higher cut leg. They help cover up while maintaining a modern style. Bikinis are super versatile and flatter all body types, making them a good option for most easy, breezy outfits.

Illumination Hi Cut

Hi-Cut panties are a mix between Bikinis and Briefs, providing more coverage than a Bikini at the tummy and back but not quite as much as a Brief. Hi-Cut panties also sit higher up on the thigh which makes your legs look longer. Hi-Cut panties are a perfect partner for high-waisted pants and skirts.

Illumination Brief

Briefs offer the most all-around coverage. Designed for comfort and fit above all else, they usually sit higher on the waist. They have a simple silhouette and typically come in soft fabrics like cotton, nylon, or microfiber. Briefs are a great no-show option to wear under clothing that skims and glides, like dresses and skirts.

Illumination Hipster

Hipsters are most like a Bikini, but they offer slightly more coverage with wider sides and lower cut legs. Hipsters also tend to have a low rise, sitting just below the waist which makes them a great option for low-rise jeans and pants.
