Calvin Klein Underwear, curated by Reiss, is a collection of lingerie designed to elevate the underwear drawer and work perfectly beneath your existing Reiss garments. Feel comfortable from the first layer. Complete your beach-day packing list with the black Sheer Knit Pants. They’re a high-rise, straight leg shape that elongates the profile. An elasticated waistband is added for a comfortable, effortless wear. Throw on over your swimwear for a chic warm weather edit.
