C-IN2 C-Theory Brief
Let it all hang out in the C-IN2 C-Theory Brief.
This sexy, color-forward silhouette adds a playful touch to your daily wear. The low-rise fit elongates your legs and leaves just enough to the imagination — exactly how we like it. Choose from a contrast waistband or an all-over monochrome, both offering a cushioned elastic waistband that's stretchy and soft. And let's not forget, this brief enhances your backside like no other.
The C-Theory has a playful vibe that’s hard to miss. As a brief, it offers the practicality of a daily essential, especially if you grab a few colors. Add the buttery soft cotton feel you love, and it’s easy to see why you’ll want to taste the rainbow.
- Low-rise fit — sits just below your natural waistline
- Ultra-soft feel — cotton brings the softness you love
- Contoured pouch — supportive and ultra-flattering
- Slimming waistband — bold and branded
