Why Silk?
The first layer matters.
Naturally breathable and smooth against the skin, our lingerie is fully silk-lined to place silk where it belongs: closest to the body.

Notes from the women who wear Black Heart.
★★★★★The silk lays flat under clothes and doesn’t show through. I’ve worn this during the day and it stays comfortable the entire time.
