Only Hearts Frankie Flannel Bias Slip
The Only Hearts Frankie Flannel Bias Slip is a one-of-a-kind piece in the truest sense. Cut on the bias from 100% cotton flannel, it drapes with a fluid, effortless movement that you don’t expect from flannel — warm and cozy, yet surprisingly graceful. The loose silhouette, adjustable straps, and ivory trim at the bodice give it a delicate, feminine edge that sets it apart from anything in your sleepwear drawer.
Flirty, soft, and made to be lived in. This is the slip you reach for on cold mornings and slow evenings alike — the kind of piece that only gets better with wear. Handcrafted in New York City’s Garment District with Only Hearts’ signature care.
