Classic Style & Comfort Since the 60s, Calvin Klein has been reimagining the basics... and making them basically irresistible. This collection of CK panties are equal parts seduction and stye: Sheer-lace thongs and bikinis, equally lacy hipsters, mesh-panel bikini briefs, and even a few cotton bralettes to round out the collection. With a cool, casual minimalism, Calvin Klein panties offer the utmost in comfort, confidence, and big-time sensuality.
